The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
* It was found that the Linux kernel's IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841, Important)
* Several Moderate and Low impact security issues were found in the Linux kernel. Space precludes documenting each of these issues in this advisory. Refer to the CVE links in the References section for a description of each of these vulnerabilities.

(CVE-2016-2053)\n\n - Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor. (CVE-2016-2384)\n\n - The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface. (CVE-2016-4569)\n\n - sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.\n (CVE-2016-4578)\n\n - arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux kernel through 4.7 on PowerPC platforms, when CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS users to cause a denial of service (host OS infinite loop) by making a H_CEDE hypercall during the existence of a suspended transaction. (CVE-2016-5412)\n\n - drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel before 4.5.1 allows local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation. (CVE-2016-6327)\n\n - Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 4.7 allows 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. (CVE-2016-6480)\n\n - fs/nfs/nfs4proc.c in the NFS client in the Linux kernel before 4.2.2 does not properly initialize memory for migration recovery operations, which allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) via crafted network traffic. (CVE-2015-8746)\n\n - drivers/infiniband/hw/cxgb3/iwch_cm.c in the Linux kernel before 4.5 does not properly identify error conditions, which allows remote attackers to execute arbitrary code or cause a denial of service (use- after-free) via crafted packets. (CVE-2015-8812)\n\n - The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move. (CVE-2016-3070)\n\n - The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute untrusted code by appending ACPI tables to the initrd. (CVE-2016-3699)\n\n - The IPv6 stack in the Linux kernel before 4.3.3 mishandles options data, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841)\n\n - Use-after-free vulnerability in mm/percpu.c in the Linux kernel through 4.6 allows local users to cause a denial of service (BUG) or possibly have unspecified other impact via crafted use of the mmap and bpf system calls.

as referenced in the ELSA-2016-3644 advisory.\n\n - The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling. (CVE-2016-1583)\n\n - The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel before 4.2 allows 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. (CVE-2015-8956)\n\n - The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c. (CVE-2016-2053)\n\n - The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface. (CVE-2016-4569)\n\n - sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.\n (CVE-2016-4578)\n\n - Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 4.7 allows 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. (CVE-2016-6480)\n\n - The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move. (CVE-2016-3070)\n\n - The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute untrusted code by appending ACPI tables to the initrd.

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. 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\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

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.

(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 - CVE-2016-6327: drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation (bnc#994748).\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-2016-6130: Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by changing a certain length value, aka a 'double fetch' vulnerability (bnc#987542).\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\nThe following non-security bugs were fixed :\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 -

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.

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. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. 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\n - A flaw was found in the USB-MIDI Linux kernel driver: a double-free error could be triggered for the 'umidi' object.
