(CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic.

An attacker can leverage the\n generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of\n fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing\n fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed,\n unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to\n DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is\n communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain\n extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between\n Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU\n smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as\n required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received\n ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with\n extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS\n scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they\n implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the\n aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an\n attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message\n with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned\n routers will themselves be the ones dropping their own traffic.

A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).\n(CVE-2016-2069, Moderate)\n\n* A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480, Moderate)\n\n* It was found that when the gcc stack protector was enabled, reading the / proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks. (CVE-2016-7042, Moderate)\n\n* It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.\n(CVE-2016-7097, Moderate)\n\n* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().

bugs were fixed :\n\n - CVE-2013-5634: arch/arm/kvm/arm.c in the Linux kernel on the ARM platform, when KVM is used, allowed host OS users to cause a denial of service (NULL pointer dereference, OOPS, and host OS crash) or possibly have unspecified other impact by omitting vCPU initialization before a KVM_GET_REG_LIST ioctl call. (bsc#994758)\n\n - CVE-2016-2069: Race condition in arch/x86/mm/tlb.c in the Linux kernel allowed local users to gain privileges by triggering access to a paging structure by a different CPU (bnc#963767).\n\n - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel used an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517).\n\n - CVE-2016-7097: The filesystem implementation in the Linux kernel preserved the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925).\n\n - CVE-2016-8658: Stack-based buffer overflow in the brcmf_cfg80211_start_ap function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021 1.c in the Linux kernel allowed local users to cause a denial of service (system crash) or possibly have unspecified other impact via a long SSID Information Element in a command to a Netlink socket (bnc#1004462).\n\n - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).\n\n -

security bugs were fixed :\n\n - CVE-2013-5634: arch/arm/kvm/arm.c in the Linux kernel on\n the ARM platform, when KVM is used, allowed host OS\n users to cause a denial of service (NULL pointer\n dereference, OOPS, and host OS crash) or possibly have\n unspecified other impact by omitting vCPU initialization\n before a KVM_GET_REG_LIST ioctl call. (bsc#994758)\n\n - CVE-2016-2069: Race condition in arch/x86/mm/tlb.c in\n the Linux kernel allowed local users to gain privileges\n by triggering access to a paging structure by a\n different CPU (bnc#963767).\n\n - CVE-2016-7042: The proc_keys_show function in\n security/keys/proc.c in the Linux kernel used an\n incorrect buffer size for certain timeout data, which\n allowed local users to cause a denial of service (stack\n memory corruption and panic) by reading the /proc/keys\n file (bnc#1004517).\n\n - CVE-2016-7097: The filesystem implementation in the\n Linux kernel preserved the setgid bit during a setxattr\n call, which allowed local users to gain group privileges\n by leveraging the existence of a setgid program with\n restrictions on execute permissions (bnc#995968).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in\n net/bluetooth/rfcomm/sock.c in the Linux kernel allowed\n local users to obtain sensitive information or cause a\n denial of service (NULL pointer dereference) via vectors\n involving a bind system call on a Bluetooth RFCOMM\n socket (bnc#1003925).\n\n - CVE-2016-8658: Stack-based buffer overflow in the\n brcmf_cfg80211_start_ap function in\n drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021\n 1.c in the Linux kernel allowed local users to cause a\n denial of service (system crash) or possibly have\n unspecified other impact via a long SSID Information\n Element in a command to a Netlink socket (bnc#1004462).\n\n - CVE-2016-7425: The arcmsr_iop_message_xfer function in\n drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did\n not restrict a certain length field, which allowed local\n users to gain privileges or cause a denial of service\n (heap-based buffer overflow) via an\n ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).\n\n - CVE-2016-6327: drivers/infiniband/ulp/srpt/ib_srpt.c in\n the Linux kernel allowed local users to cause a denial\n of service (NULL pointer dereference and system crash)\n by using an ABORT_TASK command to abort a device write\n operation (bnc#994748).\n\n - CVE-2016-6828: The tcp_check_send_head function in\n include/net/tcp.h in the Linux kernel did not properly\n maintain certain SACK state after a failed data copy,\n which allowed local users to cause a denial of service\n (tcp_xmit_retransmit_queue use-after-free and system\n crash) via a crafted SACK option (bnc#994296).\n\n - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel\n did not properly determine the rate of challenge ACK\n segments, which made it easier for remote attackers to\n hijack TCP sessions via a blind in-window attack\n (bnc#989152).\n\n - CVE-2016-6130: Race condition in the sclp_ctl_ioctl_sccb\n function in drivers/s390/char/sclp_ctl.c in the Linux\n kernel allowed local users to obtain sensitive\n information from kernel memory by changing a certain\n length value, aka a 'double fetch' vulnerability\n (bnc#987542).\n\n - CVE-2016-6480: Race condition in the ioctl_send_fib\n function in drivers/scsi/aacraid/commctrl.c in the Linux\n kernel allowed local users to cause a denial of service\n (out-of-bounds access or system crash) by changing a\n certain size value, aka a 'double fetch' vulnerability\n (bnc#991608).\n\nThe following non-security bugs were fixed :\n\n - aacraid: Fix RRQ overload (bsc#1003079).\n\n - acpi / pm: Ignore wakeup setting if the ACPI companion\n can't wake up (FATE#315621).\n\n - af_vsock: Shrink the area influenced by prepare_to_wait\n (bsc#994520).\n\n - apparmor: add missing id bounds check on dfa\n verification (bsc#1000304).\n\n - apparmor: check that xindex is in trans_table bounds\n (bsc#1000304).\n\n - apparmor: do not check for vmalloc_addr if kvzalloc()\n failed (bsc#1000304).\n\n - apparmor: do not expose kernel stack (bsc#1000304).\n\n - apparmor: ensure the target profile name is always\n audited (bsc#1000304).\n\n - apparmor: exec should not be returning ENOENT when it\n denies (bsc#1000304).\n\n - apparmor: fix arg_size computation for when setprocattr\n is null terminated (bsc#1000304).\n\n - apparmor: fix audit full profile hname on successful\n load (bsc#1000304).\n\n - apparmor: fix change_hat not finding hat after policy\n replacement (bsc#1000287).\n\n - apparmor: fix disconnected bind mnts reconnection\n (bsc#1000304).\n\n - apparmor: fix log failures for all profiles in a set\n (bsc#1000304).\n\n - apparmor: fix module parameters can be changed after\n policy is locked (bsc#1000304).\n\n - apparmor: fix oops in profile_unpack() when policy_db is\n not present (bsc#1000304).\n\n - apparmor: fix oops, validate buffer size in\n apparmor_setprocattr() (bsc#1000304).\n\n - apparmor: fix put() parent ref after updating the active\n ref (bsc#1000304).\n\n - apparmor: fix refcount bug in profile replacement\n (bsc#1000304).\n\n - apparmor: fix refcount race when finding a child profile\n (bsc#1000304).\n\n - apparmor: fix replacement bug that adds new child to old\n parent (bsc#1000304).\n\n - apparmor: fix uninitialized lsm_audit member\n (bsc#1000304).\n\n - apparmor: fix update the mtime of the profile file on\n replacement (bsc#1000304).\n\n - apparmor: internal paths should be treated as\n disconnected (bsc#1000304).\n\n - apparmor: use list_next_entry instead of list_entry_next\n (bsc#1000304).\n\n - arm64: Ensure pmd_present() returns false after\n pmd_mknotpresent() (Automatic NUMA Balancing\n (fate#315482)).\n\n - arm64: mm: remove broken &= operator from\n pmd_mknotpresent (Automatic NUMA Balancing\n (fate#315482)).\n\n - avoid dentry crash triggered by NFS (bsc#984194).\n\n - be2net: Do not leak iomapped memory on removal\n (bsc#921784 FATE#318561).\n\n - be2net: fix BE3-R FW download compatibility check\n (bsc#921784 FATE#318561).\n\n - be2net: fix wrong return value in\n be_check_ufi_compatibility() (bsc#921784 FATE#318561).\n\n - be2net: remove vlan promisc capability from VF's profile\n descriptors (bsc#921784 FATE#318561).\n\n -

For the PowerPC64 a new 'bigmem' flavor has been added to support big Power machines. (FATE#319026) The following security bugs were fixed :\n\n - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517).\n\n - CVE-2016-7097: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925).\n\n - CVE-2016-7117: Use-after-free vulnerability in the\n __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077).\n\n - CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel allowed local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721 (bnc#994759).\n\n - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).\n\n - CVE-2016-3841: The IPv6 stack in the Linux kernel mishandled options data, which allowed local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call (bnc#992566).\n\n - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296).\n\n - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly determine the rate of challenge ACK segments, which made it easier for remote attackers to hijack TCP sessions via a blind in-window attack (bnc#989152).\n\n - CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a 'double fetch' vulnerability (bnc#991608).\n\n - CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to provide a crafted offset value that leads to crossing a ruleset blob boundary (bnc#986365).\n\n - CVE-2015-7513: arch/x86/kvm/x86.c in the Linux kernel did not reset the PIT counter values during state restoration, which allowed guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via a zero value, related to the kvm_vm_ioctl_set_pit and kvm_vm_ioctl_set_pit2 functions (bnc#960689).\n\n - CVE-2013-4312: The Linux kernel allowed local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c (bnc#839104 bsc#922947 bsc#968014).\n\nThe update package also includes non-security fixes.

installation on the remote host is affected by the following vulnerabilities :\n\n - A flaw was found in the Linux kernel's handling of packets with the URG flag. Applications using the splice() and tcp_splice_read() functionality can allow a remote attacker to force the kernel to enter a condition in which it can loop indefinitely.\n\n - It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946.\n\n - It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.\n\n - A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.\n\n - When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.\n\n - A flaw was discovered in the way the Linux kernel dealt with paging structures.

Applications using the\n splice() and tcp_splice_read() functionality can allow\n a remote attacker to force the kernel to enter a\n condition in which it can loop indefinitely.\n\n - It was discovered that a remote attacker could leverage\n the generation of IPv6 atomic fragments to trigger the\n use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is\n not needed) and could subsequently perform any type of\n a fragmentation-based attack against legacy IPv6 nodes\n that do not implement RFC6946.\n\n - It was found that the blk_rq_map_user_iov() function in\n the Linux kernel's block device implementation did not\n properly restrict the type of iterator, which could\n allow a local attacker to read or write to arbitrary\n kernel memory locations or cause a denial of service\n (use-after-free) by leveraging write access to a\n /dev/sg device.\n\n - A flaw was found in the Linux kernel's implementation\n of the SCTP protocol. A remote attacker could trigger\n an out-of-bounds read with an offset of up to 64kB\n potentially causing the system to crash.\n\n - A flaw was found in the Linux networking subsystem\n where a local attacker with CAP_NET_ADMIN capabilities\n could cause an out-of-bounds memory access by creating\n a smaller-than-expected ICMP header and sending to its\n destination via sendto().\n\n - It was found that when file permissions were modified\n via chmod and the user modifying them was not in the\n owning group or capable of CAP_FSETID, the setgid bit\n would be cleared. Setting a POSIX ACL via setxattr sets\n the file permissions as well as the new ACL, but\n doesn't clear the setgid bit in a similar way. This\n could allow a local user to gain group privileges via\n certain setgid applications.\n\n - It was found that when the gcc stack protector was\n enabled, reading the /proc/keys file could cause a\n panic in the Linux kernel due to stack corruption. This\n happened because an incorrect buffer size was used to\n hold a 64-bit timeout value rendered as weeks.\n\n - A race condition flaw was found in the ioctl_send_fib()\n function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial\n of service (out-of-bounds access or system crash) by\n changing a certain size value.\n\n - When creating audit records for parameters to executed\n children processes, an attacker can convince the Linux\n kernel audit subsystem can create corrupt records which\n may allow an attacker to misrepresent or evade logging\n of executing commands.\n\n - A flaw was discovered in the way the Linux kernel dealt\n with paging structures. When the kernel invalidated a\n paging structure that was not in use locally, it could,\n in principle, race against another CPU that is\n switching to a process that uses the paging structure\n in question. A local user could use a thread running\n with a stale cached virtual->physical translation to\n potentially escalate their privileges if the\n translation in question were writable and the physical\n page got reused for something critical (for example, a\n page table).\n\n - A flaw was found in the USB-MIDI Linux kernel driver: a\n double-free error could be triggered for the 'umidi'\n object. An attacker with physical access to the system\n could use this flaw to escalate their privileges.\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from

Leap 42.1 kernel was updated to 4.1.36 to receive various\nsecurity and bugfixes.\n\nThe following security bugs were fixed :\n\n - CVE-2016-8655: A race condition in the af_packet\n packet_set_ring function could be used by local\n attackers to crash the kernel or gain privileges\n (bsc#1012754).\n\n - CVE-2016-9794: A use-after-free in ALSA pcm could lead\n to crashes or allowed local users to potentially gain\n privileges (bsc#1013533).\n\n - CVE-2015-8962: Double free vulnerability in the\n sg_common_write function in drivers/scsi/sg.c in the\n Linux kernel allowed local users to gain privileges or\n cause a denial of service (memory corruption and system\n crash) by detaching a device during an SG_IO ioctl call\n (bnc#1010501).\n\n - CVE-2016-9178: The __get_user_asm_ex macro in\n arch/x86/include/asm/uaccess.h in the Linux kernel did\n not initialize a certain integer variable, which allowed\n local users to obtain sensitive information from kernel\n stack memory by triggering failure of a get_user_ex call\n (bnc#1008650).\n\n - CVE-2016-7913: The xc2028_set_config function in\n drivers/media/tuners/tuner-xc2028.c in the Linux kernel\n allowed local users to gain privileges or cause a denial\n of service (use-after-free) via vectors involving\n omission of the firmware name from a certain data\n structure (bnc#1010478).\n\n - CVE-2016-9555: The sctp_sf_ootb function in\n net/sctp/sm_statefuns.c in the Linux kernel lacks\n chunk-length checking for the first chunk, which allowed\n remote attackers to cause a denial of service\n (out-of-bounds slab access) or possibly have unspecified\n other impact via crafted SCTP data (bnc#1011685).\n\n - CVE-2015-8963: Race condition in kernel/events/core.c in\n the Linux kernel allowed local users to gain privileges\n or cause a denial of service (use-after-free) by\n leveraging incorrect handling of an swevent data\n structure during a CPU unplug operation (bnc#1010502).\n\n - CVE-2015-8964: The tty_set_termios_ldisc function in\n drivers/tty/tty_ldisc.c in the Linux kernel allowed\n local users to obtain sensitive information from kernel\n memory by reading a tty data structure (bnc#1010507).\n\n - CVE-2016-8646: The hash_accept function in\n crypto/algif_hash.c in the Linux kernel allowed local\n users to cause a denial of service (OOPS) by attempting\n to trigger use of in-kernel hash algorithms for a socket\n that has received zero bytes of data (bnc#1010150).\n\n - CVE-2016-8633: drivers/firewire/net.c in the Linux\n kernel in certain unusual hardware configurations,\n allowed remote attackers to execute arbitrary code via\n crafted fragmented packets (bnc#1008833).\n\n - CVE-2016-8630: The x86_decode_insn function in\n arch/x86/kvm/emulate.c in the Linux kernel, when KVM is\n enabled, allowed local users to cause a denial of\n service (host OS crash) via a certain use of a ModR/M\n byte in an undefined instruction (bnc#1009222).\n\n - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux\n kernel allowed local users to bypass integer overflow\n checks, and cause a denial of service (memory\n corruption) or have unspecified other impact, by\n leveraging access to a vfio PCI device file for a\n VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine\n confusion bug (bnc#1007197).\n\n - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the\n Linux kernel misuses the kzalloc function, which allowed\n local users to cause a denial of service (integer\n overflow) or have unspecified other impact by leveraging\n access to a vfio PCI device file (bnc#1007197).\n\n - CVE-2016-7042: The proc_keys_show function in\n security/keys/proc.c in the Linux kernel through 4.8.2,\n when the GNU Compiler Collection (gcc) stack protector\n is enabled, uses an incorrect buffer size for certain\n timeout data, which allowed local users to cause a\n denial of service (stack memory corruption and panic) by\n reading the /proc/keys file (bnc#1004517).\n\n - CVE-2016-7097: The filesystem implementation in the\n Linux kernel preserves the setgid bit during a setxattr\n call, which allowed local users to gain group privileges\n by leveraging the existence of a setgid program with\n restrictions on execute permissions (bnc#995968).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in\n net/bluetooth/rfcomm/sock.c in the Linux kernel allowed\n local users to obtain sensitive information or cause a\n denial of service (NULL pointer dereference) via vectors\n involving a bind system call on a Bluetooth RFCOMM\n socket (bnc#1003925).\n\nThe following non-security bugs were fixed :\n\n - ata: ahci_xgene: dereferencing uninitialized pointer in\n probe (bsc#1006580).\n\n - blacklist.conf: add some commits (bsc#1006580)\n\n - bna: Add synchronization for tx ring (bsc#993739).\n\n - bonding: set carrier off for devices created through\n netlink (bsc#999577).\n\n - btrfs: deal with duplicates during extent_map insertion\n in btrfs_get_extent (bsc#1001171).\n\n - btrfs: deal with existing encompassing extent map in\n btrfs_get_extent() (bsc#1001171).\n\n - btrfs: fix extent tree corruption due to relocation\n (bsc#990384).\n\n - btrfs: fix races on root_log_ctx lists (bsc#1007653).\n\n - ext4: fix data exposure after a crash (bsc#1012876).\n\n - ext4: fix reference counting bug on block allocation\n error (bsc#1012876).\n\n - gre: Disable segmentation offloads w/ CSUM and we are\n encapsulated via FOU (bsc#1001486).\n\n - gro: Allow tunnel stacking in the case of FOU/GUE\n (bsc#1001486).\n\n - ipv6: send NEWLINK on RA managed/otherconf changes\n (bsc#934067).\n\n - ipv6: send only one NEWLINK when RA causes changes\n (bsc#934067).\n\n - isofs: Do not return EACCES for unknown filesystems\n (bsc#1012876).\n\n - jbd2: fix checkpoint list cleanup (bsc#1012876).\n\n - jbd2: Fix unreclaimed pages after truncate in\n data=journal mode (bsc#1010909).\n\n - locking/static_key: Fix concurrent static_key_slow_inc()\n (bsc#1006580).\n\n - mmc: Fix kabi breakage of mmc-block in 4.1.36\n (stable-4.1.36).\n\n - posix_acl: Added fix for f2fs.\n\n - Revert 'kbuild: add -fno-PIE' (stable-4.1.36).\n\n - Revert 'x86/mm: Expand the exception table logic to\n allow new handling options' (stable-4.1.36).\n\n - tunnels: Remove encapsulation offloads on decap\n (bsc#1001486).\n\n - usbhid: add ATEN CS962 to list of quirky devices\n (bsc#1007615).\n\n - vmxnet3: Wake queue from reset work (bsc#999907).\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.opensuse.org/show_bug.cgi?id=1001171\"\n );\n

A local, unprivileged user could use this flaw to cause a denial of service on the system by creating a special stack layout that would force the perf_callchain_user_64() function into an infinite loop.(CVE-2015-6526i1/4%0\n\n - A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation (i.e. the directory entry name being encoded by a bunch of NM entries). The process stops when the amount collected so far + the claimed amount in the current NM entry exceed 254. However, the value returned as the total length is the sum of *claimed* sizes, not the actual amount collected. And that's what will be passed to readdir() callback as the name length - 8Kb\n __copy_to_user() from a buffer allocated by\n __get_free_page().(CVE-2016-4913i1/4%0\n\n - The perf_trace_event_perm function in kernel/trace/trace_event_perf.c in the Linux kernel before 3.12.2 does not properly restrict access to the perf subsystem, which allows local users to enable function tracing via a crafted application.(CVE-2013-2930i1/4%0\n\n - The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server.(CVE-2019-5489i1/4%0\n\n - It was found that the espfix functionality could be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks), and using that segment on the stack. A local, unprivileged user could potentially use this flaw to leak kernel stack addresses.(CVE-2014-8133i1/4%0\n\n - An issue was discovered in the btrfs filesystem code in the Linux kernel. An out-of-bounds access is possible in write_extent_buffer() when mounting and operating a crafted btrfs image due to a lack of verification at mount time within the btrfs_read_block_groups() in fs/btrfs/extent-tree.c function. This could lead to a system crash and a denial of service.(CVE-2018-14610i1/4%0\n\n - kernel/bpf/verifier.c in the Linux kernel through 4.14.8 mishandles states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allows local users to obtain potentially sensitive address information, aka a 'pointer leak.'(CVE-2017-17864i1/4%0\n\n - drivers/hid/hid-lenovo-tpkbd.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_LENOVO_TPKBD is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.(CVE-2013-2894i1/4%0\n\n - Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux kernel allows local users to cause a denial of service (kernel memory exhaustion) via multiple read accesses to files in the /sys/class/sas_phy directory.(CVE-2018-7757i1/4%0\n\n - It was found that the original fix for CVE-2016-6786 was incomplete. There exist a race between two concurrent sys_perf_event_open() calls when both try and move the same pre-existing software group into a hardware context.(CVE-2017-6001i1/4%0\n\n - In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmp_version and snmp_helper.(CVE-2019-9162i1/4%0\n\n - An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space.(CVE-2014-4652i1/4%0\n\n - A flaw was found that the vfs_rename() function did not detect hard links on overlayfs. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to crash the system.(CVE-2016-6198i1/4%0\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications.(CVE-2016-7097i1/4%0\n\n - A flaw was found in the way the Linux kernel's Crypto subsystem handled automatic loading of kernel modules.\n A local user could use this flaw to load any installed kernel module, and thus increase the attack surface of the running kernel.(CVE-2014-9644i1/4%0\n\n - An arbitrary memory r/w access issue was found in the Linux kernel compiled with the eBPF bpf(2) system call (CONFIG_BPF_SYSCALL) support. The issue could occur due to calculation errors in the eBPF verifier module, triggered by user supplied malicious BPF program. An unprivileged user could use this flaw to escalate their privileges on a system. Setting parameter 'kernel.unprivileged_bpf_disabled=1' prevents such privilege escalation by restricting access to bpf(2) call.(CVE-2017-16995i1/4%0\n\n - A flaw was found in the implementation of associative arrays where the add_key systemcall and KEYCTL_UPDATE operations allowed for a NULL payload with a nonzero length. When accessing the payload within this length parameters value, an unprivileged user could trivially cause a NULL pointer dereference (kernel oops).(CVE-2017-15274i1/4%0\n\n - A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation.(CVE-2016-4470i1/4%0\n\n - A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system.(CVE-2016-4565i1/4%0\n\n - It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system.(CVE-2015-8215i1/4%0\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

A local, unprivileged user could use this flaw\n to cause a denial of service on the system by creating\n a special stack layout that would force the\n perf_callchain_user_64() function into an infinite\n loop.(CVE-2015-6526i1/4%0\n\n - A vulnerability was found in the Linux kernel. Payloads\n of NM entries are not supposed to contain NUL. When\n such entry is processed, only the part prior to the\n first NUL goes into the concatenation (i.e. the\n directory entry name being encoded by a bunch of NM\n entries). The process stops when the amount collected\n so far + the claimed amount in the current NM entry\n exceed 254. However, the value returned as the total\n length is the sum of *claimed* sizes, not the actual\n amount collected. And that's what will be passed to\n readdir() callback as the name length - 8Kb\n __copy_to_user() from a buffer allocated by\n __get_free_page().(CVE-2016-4913i1/4%0\n\n - The perf_trace_event_perm function in\n kernel/trace/trace_event_perf.c in the Linux kernel\n before 3.12.2 does not properly restrict access to the\n perf subsystem, which allows local users to enable\n function tracing via a crafted\n application.(CVE-2013-2930i1/4%0\n\n - The mincore() implementation in mm/mincore.c in the\n Linux kernel through 4.19.13 allowed local attackers to\n observe page cache access patterns of other processes\n on the same system, potentially allowing sniffing of\n secret information. (Fixing this affects the output of\n the fincore program.) Limited remote exploitation may\n be possible, as demonstrated by latency differences in\n accessing public files from an Apache HTTP\n Server.(CVE-2019-5489i1/4%0\n\n - It was found that the espfix functionality could be\n bypassed by installing a 16-bit RW data segment into\n GDT instead of LDT (which espfix checks), and using\n that segment on the stack. A local, unprivileged user\n could potentially use this flaw to leak kernel stack\n addresses.(CVE-2014-8133i1/4%0\n\n - An issue was discovered in the btrfs filesystem code in\n the Linux kernel.

There exist a race between two\n concurrent sys_perf_event_open() calls when both try\n and move the same pre-existing software group into a\n hardware context.(CVE-2017-6001i1/4%0\n\n - In the Linux kernel before 4.20.12,\n net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP\n NAT module has insufficient ASN.1 length checks (aka an\n array index error), making out-of-bounds read and write\n operations possible, leading to an OOPS or local\n privilege escalation. This affects snmp_version and\n snmp_helper.(CVE-2019-9162i1/4%0\n\n - An information leak flaw was found in the way the Linux\n kernel's Advanced Linux Sound Architecture (ALSA)\n implementation handled access of the user control's\n state. A local, privileged user could use this flaw to\n leak kernel memory to user space.(CVE-2014-4652i1/4%0\n\n - A flaw was found that the vfs_rename() function did not\n detect hard links on overlayfs.

A vulnerability was found in Linux kernel. There is an information leak in file 'sound/core/timer.c' of the latest mainline Linux kernel, the stack object aEURoetreadaEUR has a total size of 32 bytes. It contains a 8-bytes padding, which is not initialized but sent to user via copy_to_user(), resulting a kernel leak.(CVE-2016-4569)\n\n - A vulnerability was found in Linux kernel. There is an information leak in file sound/core/timer.c of the latest mainline Linux kernel. The stack object aEURoer1aEUR has a total size of 32 bytes. Its field aEURoeeventaEUR and aEURoevalaEUR both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.(CVE-2016-4578)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.(CVE-2016-4580)\n\n - fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls.(CVE-2016-4581)\n\n - Use after free vulnerability was found in percpu using previously allocated memory in bpf. First\n __alloc_percpu_gfp() is called, then the memory is freed with free_percpu() which triggers async pcpu_balance_work and then pcpu_extend_area_map could use a chunk after it has been freed.(CVE-2016-4794)\n\n - Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions.(CVE-2016-4805)\n\n - A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation (i.e. the directory entry name being encoded by a bunch of NM entries). The process stops when the amount collected so far + the claimed amount in the current NM entry exceed 254. However, the value returned as the total length is the sum of *claimed* sizes, not the actual amount collected. And that's what will be passed to readdir() callback as the name length - 8Kb\n __copy_to_user() from a buffer allocated by\n __get_free_page().(CVE-2016-4913)\n\n - A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems. This flaw will allow attackers to alter arbitrary kernel memory when unloading a kernel module. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated privileges.(CVE-2016-4997)\n\n - An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments.(CVE-2016-4998)\n\n - A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.(CVE-2016-5195)\n\n - It was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network.(CVE-2016-5696)\n\n - A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system.(CVE-2016-5829)\n\n - When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.(CVE-2016-6136)\n\n - It was found that the unlink and rename functionality in overlayfs did not verify the upper dentry for staleness. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to panic or crash the system.(CVE-2016-6197)\n\n - A flaw was found that the vfs_rename() function did not detect hard links on overlayfs. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to crash the system.(CVE-2016-6198)\n\n - System using the infiniband support module ib_srpt were vulnerable to a denial of service by system crash by a local attacker who is able to abort writes to a device using this initiator.(CVE-2016-6327)\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.(CVE-2016-6480)\n\n - kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 30955111.(CVE-2016-6786)\n\n - kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 31095224.(CVE-2016-6787)\n\n - A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions.\n This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.(CVE-2016-6828)\n\n - Linux kernel built with the 802.1Q/802.1ad VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local Area Network(CONFIG_VXLAN) with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack overflow issue. It could occur while receiving large packets via GRO path, as an unlimited recursion could unfold in both VLAN and TEB modules, leading to a stack corruption in the kernel.(CVE-2016-7039)\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.(CVE-2016-7042)\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared.

There is an\n information leak in file 'sound/core/timer.c' of the\n latest mainline Linux kernel, the stack object\n aEURoetreadaEUR has a total size of 32 bytes. It contains a\n 8-bytes padding, which is not initialized but sent to\n user via copy_to_user(), resulting a kernel\n leak.(CVE-2016-4569)\n\n - A vulnerability was found in Linux kernel. There is an\n information leak in file sound/core/timer.c of the\n latest mainline Linux kernel. The stack object aEURoer1aEUR\n has a total size of 32 bytes. Its field aEURoeeventaEUR and\n aEURoevalaEUR both contain 4 bytes padding. These 8 bytes\n padding bytes are sent to user without being\n initialized.(CVE-2016-4578)\n\n - The x25_negotiate_facilities function in\n net/x25/x25_facilities.c in the Linux kernel before\n 4.5.5 does not properly initialize a certain data\n structure, which allows attackers to obtain sensitive\n information from kernel stack memory via an X.25 Call\n Request.(CVE-2016-4580)\n\n - fs/pnode.c in the Linux kernel before 4.5.4 does not\n properly traverse a mount propagation tree in a certain\n case involving a slave mount, which allows local users\n to cause a denial of service (NULL pointer dereference\n and OOPS) via a crafted series of mount system\n calls.(CVE-2016-4581)\n\n - Use after free vulnerability was found in percpu using\n previously allocated memory in bpf. First\n __alloc_percpu_gfp() is called, then the memory is\n freed with free_percpu() which triggers async\n pcpu_balance_work and then pcpu_extend_area_map could\n use a chunk after it has been freed.(CVE-2016-4794)\n\n - Use-after-free vulnerability in\n drivers/net/ppp/ppp_generic.c in the Linux kernel\n before 4.5.2 allows local users to cause a denial of\n service (memory corruption and system crash, or\n spinlock) or possibly have unspecified other impact by\n removing a network namespace, related to the\n ppp_register_net_channel and ppp_unregister_channel\n functions.(CVE-2016-4805)\n\n - A vulnerability was found in the Linux kernel. Payloads\n of NM entries are not supposed to contain NUL. When\n such entry is processed, only the part prior to the\n first NUL goes into the concatenation (i.e. the\n directory entry name being encoded by a bunch of NM\n entries). The process stops when the amount collected\n so far + the claimed amount in the current NM entry\n exceed 254. However, the value returned as the total\n length is the sum of *claimed* sizes, not the actual\n amount collected. And that's what will be passed to\n readdir() callback as the name length - 8Kb\n __copy_to_user() from a buffer allocated by\n __get_free_page().(CVE-2016-4913)\n\n - A flaw was discovered in processing setsockopt for 32\n bit processes on 64 bit systems. This flaw will allow\n attackers to alter arbitrary kernel memory when\n unloading a kernel module. This action is usually\n restricted to root-privileged users but can also be\n leveraged if the kernel is compiled with CONFIG_USER_NS\n and CONFIG_NET_NS and the user is granted elevated\n privileges.(CVE-2016-4997)\n\n - An out-of-bounds heap memory access leading to a Denial\n of Service, heap disclosure, or further impact was\n found in setsockopt(). The function call is normally\n restricted to root, however some processes with\n cap_sys_admin may also be able to trigger this flaw in\n privileged container environments.(CVE-2016-4998)\n\n - A race condition was found in the way the Linux\n kernel's memory subsystem handled the copy-on-write\n (COW) breakage of private read-only memory mappings. An\n unprivileged, local user could use this flaw to gain\n write access to otherwise read-only memory mappings and\n thus increase their privileges on the\n system.(CVE-2016-5195)\n\n - It was found that the RFC 5961 challenge ACK rate\n limiting as implemented in the Linux kernel's\n networking subsystem allowed an off-path attacker to\n leak certain information about a given connection by\n creating congestion on the global challenge ACK rate\n limit counter and then measuring the changes by probing\n packets. An off-path attacker could use this flaw to\n either terminate TCP connection and/or inject payload\n into non-secured TCP connection between two endpoints\n on the network.(CVE-2016-5696)\n\n - A heap-based buffer overflow vulnerability was found in\n the Linux kernel's hiddev driver. This flaw could allow\n a local attacker to corrupt kernel memory, possible\n privilege escalation or crashing the\n system.(CVE-2016-5829)\n\n - When creating audit records for parameters to executed\n children processes, an attacker can convince the Linux\n kernel audit subsystem can create corrupt records which\n may allow an attacker to misrepresent or evade logging\n of executing commands.(CVE-2016-6136)\n\n - It was found that the unlink and rename functionality\n in overlayfs did not verify the upper dentry for\n staleness. A local, unprivileged user could use the\n rename syscall on overlayfs on top of xfs to panic or\n crash the system.(CVE-2016-6197)\n\n - A flaw was found that the vfs_rename() function did not\n detect hard links on overlayfs. A local, unprivileged\n user could use the rename syscall on overlayfs on top\n of xfs to crash the system.(CVE-2016-6198)\n\n - System using the infiniband support module ib_srpt were\n vulnerable to a denial of service by system crash by a\n local attacker who is able to abort writes to a device\n using this initiator.(CVE-2016-6327)\n\n - A race condition flaw was found in the ioctl_send_fib()\n function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial\n of service (out-of-bounds access or system crash) by\n changing a certain size value.(CVE-2016-6480)\n\n - kernel/events/core.c in the performance subsystem in\n the Linux kernel before 4.0 mismanages locks during\n certain migrations, which allows local users to gain\n privileges via a crafted application, aka Android\n internal bug 30955111.(CVE-2016-6786)\n\n - kernel/events/core.c in the performance subsystem in\n the Linux kernel before 4.0 mismanages locks during\n certain migrations, which allows local users to gain\n privileges via a crafted application, aka Android\n internal bug 31095224.(CVE-2016-6787)\n\n - A use-after-free vulnerability was found in\n tcp_xmit_retransmit_queue and other tcp_* functions.\n This condition could allow an attacker to send an\n incorrect selective acknowledgment to existing\n connections, possibly resetting a\n connection.(CVE-2016-6828)\n\n - Linux kernel built with the 802.1Q/802.1ad\n VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local\n Area Network(CONFIG_VXLAN) with Transparent Ethernet\n Bridging(TEB) GRO support, is vulnerable to a stack\n overflow issue. It could occur while receiving large\n packets via GRO path, as an unlimited recursion could\n unfold in both VLAN and TEB modules, leading to a stack\n corruption in the kernel.(CVE-2016-7039)\n\n - It was found that when the gcc stack protector was\n enabled, reading the /proc/keys file could cause a\n panic in the Linux kernel due to stack corruption. This\n happened because an incorrect buffer size was used to\n hold a 64-bit timeout value rendered as\n weeks.(CVE-2016-7042)\n\n - It was found that when file permissions were modified\n via chmod and the user modifying them was not in the\n owning group or capable of CAP_FSETID, the setgid bit\n would be cleared. Setting a POSIX ACL via setxattr sets\n the file permissions as well as the new ACL, but\n doesn't clear the setgid bit in a similar way. This\n could allow a local user to gain group privileges via\n certain setgid applications.(CVE-2016-7097)\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576. (CVE-2016-10088)\n\n - The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr call, which allows local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions. (CVE-2016-7097)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function.

(CVE-2016-3951)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS memory consumption) by leveraging the mishandling of page references. (CVE-2017-2596)\n\n - arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in certain error cases, which allows local users to obtain sensitive information from kernel stack memory via a crafted application. (CVE-2016-9756)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability.

(CVE-2017-2596)\n\n - arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in\n certain error cases, which allows local users to obtain sensitive information from kernel stack memory via\n a crafted application. (CVE-2016-9756)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to\n cause a denial of service (system crash) via a crafted application that makes sendto system calls, related\n to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the\n relationship between the minimum fragment length and the maximum packet size, which allows local users to\n gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN\n capability. (CVE-2016-8632)\n\n - The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not\n initialize a certain integer variable, which allows local users to obtain sensitive information from\n kernel stack memory by triggering failure of a get_user_ex call. (CVE-2016-9178)\n\n - The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6\n mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via\n filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba.\n (CVE-2015-8952)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1\n allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system\n crash) via a crafted endpoints value in a USB device descriptor. (CVE-2016-3140)\n\n - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in\n required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have\n unspecified other impact via crafted system calls. (CVE-2017-6345)\n\n - The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows\n attackers to cause a denial of service (system crash) via (1) an application that makes crafted system\n calls or possibly (2) IPv4 traffic with invalid IP options.

mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c.

CVE-2016-6828: The tcp_check_send_head function in\n include/net/tcp.h in the Linux kernel did not properly\n maintain certain SACK state after a failed data copy,\n which allowed local users to cause a denial of service\n (tcp_xmit_retransmit_queue use-after-free and system\n crash) via a crafted SACK option (bnc#994296).\n\nThe update package also includes non-security fixes. See advisory for\ndetails.\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the SUSE security advisory. Tenable\nhas attempted to automatically clean and format it as much as possible\nwithout introducing additional issues.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n

Also rw_verify_area() makes extended checks, for example, that the size of the access doesn't cause overflow of the provided offset limits. This integer overflow in fs/aio.c in the Linux kernel before 3.4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. (CVE-2012-6701)\n\n - Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. NOTE:\n this vulnerability exists because of a CVE-2012-6701 regression. (CVE-2015-8830)\n\n - It was discovered that a remote attacker could leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and could subsequently perform any type of a fragmentation-based attack against legacy IPv6 nodes that do not implement RFC6946. (CVE-2016-10142)\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value. (CVE-2016-6480)\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.\n (CVE-2016-7042)\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way. This could allow a local user to gain group privileges via certain setgid applications. (CVE-2016-7097)\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399)\n\n - A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. (CVE-2016-8650)\n\n - Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely.\n (CVE-2017-0861)\n\n - A race condition issue was found in the way the raw packet socket implementation in the Linux kernel networking subsystem handled synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this to waste resources in the kernel's ring buffer or possibly cause an out-of-bounds read on the heap leading to a system crash. (CVE-2017-1000111)\n\n - A use-after-free flaw was found in the Netlink functionality of the Linux kernel networking subsystem.\n Due to the insufficient cleanup in the mq_notify function, a local attacker could potentially use this flaw to escalate their privileges on the system.\n (CVE-2017-11176)\n\n - It was found that in the Linux kernel through v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page.\n bio_add_pc_page() merges them into one, but the page reference is never dropped, causing a memory leak and possible system lockup due to out-of-memory condition.\n (CVE-2017-12190)\n\n - A divide-by-zero vulnerability was found in the\n __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. (CVE-2017-14106)\n\n - A non-privileged user is able to mount a fuse filesystem on RHEL 6 or 7 and crash a system if an application punches a hole in a file that does not end aligned to a page boundary. (CVE-2017-15121)\n\n - A use-after-free vulnerability was found when issuing an ioctl to a sound device. This could allow a user to exploit a race condition and create memory corruption or possibly privilege escalation. (CVE-2017-15265)\n\n - The Linux kernel, before version 4.14.3, is vulnerable to a denial of service in drivers/md/dm.c:dm_get_from_kobject() which can be caused by local users leveraging a race condition with\n __dm_destroy() during creation and removal of DM devices. Only privileged local users (with CAP_SYS_ADMIN capability) can directly perform the ioctl operations for dm device creation and removal and this would typically be outside the direct control of the unprivileged attacker. (CVE-2017-18203)\n\n - A race condition leading to a NULL pointer dereference was found in the Linux kernel's Link Layer Control implementation. A local attacker with access to ping sockets could use this flaw to crash the system.\n (CVE-2017-2671)\n\n - It was found that the original fix for CVE-2016-6786 was incomplete. There exist a race between two concurrent sys_perf_event_open() calls when both try and move the same pre-existing software group into a hardware context. (CVE-2017-6001)\n\n - A flaw was found in the Linux kernel's handling of packets with the URG flag. Applications using the splice() and tcp_splice_read() functionality could allow a remote attacker to force the kernel to enter a condition in which it could loop indefinitely.\n (CVE-2017-6214)\n\n - Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely. (CVE-2017-7541)\n\n - An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542)\n\n - Incorrect error handling in the set_mempolicy() and mbind() compat syscalls in 'mm/mempolicy.c' in the Linux kernel allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. (CVE-2017-7616)\n\n - The mm subsystem in the Linux kernel through 4.10.10 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c. (CVE-2017-7889)\n\n - The IPv6 fragmentation implementation in the Linux kernel does not consider that the nexthdr field may be associated with an invalid option, which allows local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-9074)\n\n - In the Linux kernel versions 4.12, 3.10, 2.6, and possibly earlier, a race condition vulnerability exists in the sound system allowing for a potential deadlock and memory corruption due to use-after-free condition and thus denial of service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2018-1000004)\n\n - A null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in the Linux kernel allows a local user to cause a denial of service by a number of certain crafted system calls. (CVE-2018-1130)\n\n - Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub- operations. These sub-operations allow the processor to hand-off address generation logic into these sub- operations for optimized writes. Both of these sub- operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126)\n\n - Microprocessors use a load port subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPUs pipelines. Stale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side- channel. (CVE-2018-12127)\n\n - A flaw was found in the implementation of the fill buffer, a mechanism used by modern CPUs when a cache- miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer.\n (CVE-2018-12130)\n\n - A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. (CVE-2018-13405)\n\n - A Floating Point Unit (FPU) state information leakage flaw was found in the way the Linux kernel saved and restored the FPU state during task switch. Linux kernels that follow the Lazy FPU Restore scheme are vulnerable to the FPU state information leakage issue. An unprivileged local attacker could use this flaw to read FPU state bits by conducting targeted cache side-channel attacks, similar to the Meltdown vulnerability disclosed earlier this year. (CVE-2018-3665)\n\n - An error in the _sctp_make_chunk() function (net/sctp/sm_make_chunk.c) when handling SCTP, packet length can be exploited by a malicious local user to cause a kernel crash and a DoS. (CVE-2018-5803)\n\n - ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access. (CVE-2018-7566)\n\n - Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

This integer\n overflow in fs/aio.c in the Linux kernel before 3.4.1\n allows local users to cause a denial of service or\n possibly have unspecified other impact via a large AIO\n iovec. (CVE-2012-6701)\n\n - Integer overflow in the aio_setup_single_vector function\n in fs/aio.c in the Linux kernel 4.0 allows local users\n to cause a denial of service or possibly have\n unspecified other impact via a large AIO iovec. NOTE:\n this vulnerability exists because of a CVE-2012-6701\n regression. (CVE-2015-8830)\n\n - It was discovered that a remote attacker could leverage\n the generation of IPv6 atomic fragments to trigger the\n use of fragmentation in an arbitrary IPv6 flow (in\n scenarios in which actual fragmentation of packets is\n not needed) and could subsequently perform any type of a\n fragmentation-based attack against legacy IPv6 nodes\n that do not implement RFC6946. (CVE-2016-10142)\n\n - A race condition flaw was found in the ioctl_send_fib()\n function in the Linux kernel's aacraid implementation. A\n local attacker could use this flaw to cause a denial of\n service (out-of-bounds access or system crash) by\n changing a certain size value. (CVE-2016-6480)\n\n - It was found that when the gcc stack protector was\n enabled, reading the /proc/keys file could cause a panic\n in the Linux kernel due to stack corruption. This\n happened because an incorrect buffer size was used to\n hold a 64-bit timeout value rendered as weeks.\n (CVE-2016-7042)\n\n - It was found that when file permissions were modified\n via chmod and the user modifying them was not in the\n owning group or capable of CAP_FSETID, the setgid bit\n would be cleared. Setting a POSIX ACL via setxattr sets\n the file permissions as well as the new ACL, but doesn't\n clear the setgid bit in a similar way. This could allow\n a local user to gain group privileges via certain setgid\n applications. (CVE-2016-7097)\n\n - A flaw was found in the Linux networking subsystem where\n a local attacker with CAP_NET_ADMIN capabilities could\n cause an out-of-bounds memory access by creating a\n smaller-than-expected ICMP header and sending to its\n destination via sendto(). (CVE-2016-8399)\n\n - A flaw was found in the Linux kernel key management\n subsystem in which a local attacker could crash the\n kernel or corrupt the stack and additional memory\n (denial of service) by supplying a specially crafted RSA\n key. This flaw panics the machine during the\n verification of the RSA key. (CVE-2016-8650)\n\n - Use-after-free vulnerability in the snd_pcm_info()\n function in the ALSA subsystem in the Linux kernel\n allows attackers to induce a kernel memory corruption\n and possibly crash or lock up a system. Due to the\n nature of the flaw, a privilege escalation cannot be\n fully ruled out, although we believe it is unlikely.\n (CVE-2017-0861)\n\n - A race condition issue was found in the way the raw\n packet socket implementation in the Linux kernel\n networking subsystem handled synchronization. A local\n user able to open a raw packet socket (requires the\n CAP_NET_RAW capability) could use this to waste\n resources in the kernel's ring buffer or possibly cause\n an out-of-bounds read on the heap leading to a system\n crash. (CVE-2017-1000111)\n\n - A use-after-free flaw was found in the Netlink\n functionality of the Linux kernel networking subsystem.\n Due to the insufficient cleanup in the mq_notify\n function, a local attacker could potentially use this\n flaw to escalate their privileges on the system.\n (CVE-2017-11176)\n\n - It was found that in the Linux kernel through v4.14-rc5,\n bio_map_user_iov() and bio_unmap_user() in 'block/bio.c'\n do unbalanced pages refcounting if IO vector has small\n consecutive buffers belonging to the same page.\n bio_add_pc_page() merges them into one, but the page\n reference is never dropped, causing a memory leak and\n possible system lockup due to out-of-memory condition.\n (CVE-2017-12190)\n\n - A divide-by-zero vulnerability was found in the\n __tcp_select_window function in the Linux kernel. This\n can result in a kernel panic causing a local denial of\n service. (CVE-2017-14106)\n\n - A non-privileged user is able to mount a fuse filesystem\n on RHEL 6 or 7 and crash a system if an application\n punches a hole in a file that does not end aligned to a\n page boundary. (CVE-2017-15121)\n\n - A use-after-free vulnerability was found when issuing an\n ioctl to a sound device. This could allow a user to\n exploit a race condition and create memory corruption or\n possibly privilege escalation. (CVE-2017-15265)\n\n - The Linux kernel, before version 4.14.3, is vulnerable\n to a denial of service in\n drivers/md/dm.c:dm_get_from_kobject() which can be\n caused by local users leveraging a race condition with\n __dm_destroy() during creation and removal of DM\n devices. Only privileged local users (with CAP_SYS_ADMIN\n capability) can directly perform the ioctl operations\n for dm device creation and removal and this would\n typically be outside the direct control of the\n unprivileged attacker. (CVE-2017-18203)\n\n - A race condition leading to a NULL pointer dereference\n was found in the Linux kernel's Link Layer Control\n implementation. A local attacker with access to ping\n sockets could use this flaw to crash the system.\n (CVE-2017-2671)\n\n - It was found that the original fix for CVE-2016-6786 was\n incomplete. There exist a race between two concurrent\n sys_perf_event_open() calls when both try and move the\n same pre-existing software group into a hardware\n context. (CVE-2017-6001)\n\n - A flaw was found in the Linux kernel's handling of\n packets with the URG flag. Applications using the\n splice() and tcp_splice_read() functionality could allow\n a remote attacker to force the kernel to enter a\n condition in which it could loop indefinitely.\n (CVE-2017-6214)\n\n - Kernel memory corruption due to a buffer overflow was\n found in brcmf_cfg80211_mgmt_tx() function in Linux\n kernels from v3.9-rc1 to v4.13-rc1. The vulnerability\n can be triggered by sending a crafted NL80211_CMD_FRAME\n packet via netlink. This flaw is unlikely to be\n triggered remotely as certain userspace code is needed\n for this. An unprivileged local user could use this flaw\n to induce kernel memory corruption on the system,\n leading to a crash. Due to the nature of the flaw,\n privilege escalation cannot be fully ruled out, although\n it is unlikely. (CVE-2017-7541)\n\n - An integer overflow vulnerability in\n ip6_find_1stfragopt() function was found. A local\n attacker that has privileges (of CAP_NET_RAW) to open\n raw socket can cause an infinite loop inside the\n ip6_find_1stfragopt() function. (CVE-2017-7542)\n\n - Incorrect error handling in the set_mempolicy() and\n mbind() compat syscalls in 'mm/mempolicy.c' in the Linux\n kernel allows local users to obtain sensitive\n information from uninitialized stack data by triggering\n failure of a certain bitmap operation. (CVE-2017-7616)\n\n - The mm subsystem in the Linux kernel through 4.10.10\n does not properly enforce the CONFIG_STRICT_DEVMEM\n protection mechanism, which allows local users to read\n or write to kernel memory locations in the first\n megabyte (and bypass slab-allocation access\n restrictions) via an application that opens the /dev/mem\n file, related to arch/x86/mm/init.c and\n drivers/char/mem.c. (CVE-2017-7889)\n\n - The IPv6 fragmentation implementation in the Linux\n kernel does not consider that the nexthdr field may be\n associated with an invalid option, which allows local\n users to cause a denial of service (out-of-bounds read\n and BUG) or possibly have unspecified other impact via\n crafted socket and send system calls. Due to the nature\n of the flaw, privilege escalation cannot be fully ruled\n out, although we believe it is unlikely. (CVE-2017-9074)\n\n - In the Linux kernel versions 4.12, 3.10, 2.6, and\n possibly earlier, a race condition vulnerability exists\n in the sound system allowing for a potential deadlock\n and memory corruption due to use-after-free condition\n and thus denial of service. Due to the nature of the\n flaw, privilege escalation cannot be fully ruled out,\n although we believe it is unlikely. (CVE-2018-1000004)\n\n - A null pointer dereference in dccp_write_xmit() function\n in net/dccp/output.c in the Linux kernel allows a local\n user to cause a denial of service by a number of certain\n crafted system calls. (CVE-2018-1130)\n\n - Modern Intel microprocessors implement hardware-level\n micro-optimizations to improve the performance of\n writing data back to CPU caches. The write operation is\n split into STA (STore Address) and STD (STore Data) sub-\n operations. These sub-operations allow the processor to\n hand-off address generation logic into these sub-\n operations for optimized writes. Both of these sub-\n operations write to a shared distributed processor\n structure called the 'processor store buffer'. As a\n result, an unprivileged attacker could use this flaw to\n read private data resident within the CPU's processor\n store buffer. (CVE-2018-12126)\n\n - Microprocessors use a load port subcomponent to\n perform load operations from memory or IO. During a load\n operation, the load port receives data from the memory\n or IO subsystem and then provides the data to the CPU\n registers and operations in the CPUs pipelines. Stale\n load operations results are stored in the 'load port'\n table until overwritten by newer operations. Certain\n load-port operations triggered by an attacker can be\n used to reveal data about previous stale requests\n leaking data back to the attacker via a timing side-\n channel. (CVE-2018-12127)\n\n - A flaw was found in the implementation of the fill\n buffer, a mechanism used by modern CPUs when a cache-\n miss is made on L1 CPU cache. If an attacker can\n generate a load operation that would create a page\n fault, the execution will continue speculatively with\n incorrect data from the fill buffer while the data is\n fetched from higher level caches. This response time can\n be measured to infer data in the fill buffer.\n (CVE-2018-12130)\n\n - A vulnerability was found in the\n fs/inode.c:inode_init_owner() function logic of the\n LInux kernel that allows local users to create files\n with an unintended group ownership and with group\n execution and SGID permission bits set, in a scenario\n where a directory is SGID and belongs to a certain group\n and is writable by a user who is not a member of this\n group. This can lead to excessive permissions granted in\n case when they should not. (CVE-2018-13405)\n\n - A Floating Point Unit (FPU) state information leakage\n flaw was found in the way the Linux kernel saved and\n restored the FPU state during task switch. Linux kernels\n that follow the Lazy FPU Restore scheme are vulnerable\n to the FPU state information leakage issue. An\n unprivileged local attacker could use this flaw to read\n FPU state bits by conducting targeted cache side-channel\n attacks, similar to the Meltdown vulnerability disclosed\n earlier this year. (CVE-2018-3665)\n\n - An error in the _sctp_make_chunk() function\n (net/sctp/sm_make_chunk.c) when handling SCTP, packet\n length can be exploited by a malicious local user to\n cause a kernel crash and a DoS. (CVE-2018-5803)\n\n - ALSA sequencer core initializes the event pool on demand\n by invoking snd_seq_pool_init() when the first write\n happens and the pool is empty. A user can reset the pool\n size manually via ioctl concurrently, and this may lead\n to UAF or out-of-bound access. (CVE-2018-7566)\n\n - Uncacheable memory on some microprocessors utilizing\n speculative execution may allow an authenticated user to\n potentially enable information disclosure via a side\n channel with local access.
