A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.\n\nSecurity Fix(es) :\n\n* A flaw was found in the Linux kernel's key management system where it was possible for an attacker to escalate privileges or crash the machine. If a user key gets negatively instantiated, an error code is cached in the payload area. A negatively instantiated key may be then be positively instantiated by updating it with valid data. However, the ->update key type method must be aware that the error code may be there. (CVE-2015-8539, Important)\n\n* It was found that fanout_add() in 'net/packet/af_packet.c' in the Linux kernel, before version 4.13.6, allows local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free bug.\n(CVE-2017-15649, Important)\n\n* A vulnerability was found in the Linux kernel where the keyctl_set_reqkey_keyring() function leaks the thread keyring.

This\n affects the keyring key type and thus key addition and\n link creation operations may cause the kernel to panic.\n (CVE-2017-12193)\n\n - It was found that fanout_add() in\n 'net/packet/af_packet.c' in the Linux kernel, before\n version 4.13.6, allows local users to gain privileges\n via crafted system calls that trigger mishandling of\n packet_fanout data structures, because of a race\n condition (involving fanout_add and packet_do_bind) that\n leads to a use-after-free bug. (CVE-2017-15649)\n\n - A vulnerability was found in the Linux kernel where the\n keyctl_set_reqkey_keyring() function leaks the thread\n keyring. This allows an unprivileged local user to\n exhaust kernel memory and thus cause a DoS.\n (CVE-2017-7472)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"http://security.gd-linux.com/notice/NS-SA-2019-0014\");\n script_set_attribute(attribute:\"solution\", value:\n\"Upgrade the vulnerable CGSL kernel packages.

There are three primary\nvariants of the issue which differ in the way the speculative\nexecution can be exploited.\n\nNote: This issue is present in hardware and cannot be fully fixed via\nsoftware update. The updated kernel packages provide software\nmitigation for this hardware issue at a cost of potential performance\npenalty.\n\n* Variant CVE-2017-5715 triggers the speculative execution by\nutilizing branch target injection. It relies on the presence of a\nprecisely-defined instruction sequence in the privileged code as well\nas the fact that memory accesses may cause allocation into the\nmicroprocessor's data cache even for speculatively executed\ninstructions that never actually commit (retire). As a result, an\nunprivileged attacker could use this flaw to cross the syscall and\nguest/host boundaries and read privileged memory by conducting\ntargeted cache side-channel attacks. This fix specifically addresses\nS390 processors. (CVE-2017-5715, Important)\n\n* Variant CVE-2017-5753 triggers the speculative execution by\nperforming a bounds-check bypass.

As a result, an\nunprivileged attacker could use this flaw to cross the syscall\nboundary and read privileged memory by conducting targeted cache\nside-channel attacks. This fix specifically addresses S390 and PowerPC\nprocessors. (CVE-2017-5753, Important)\n\n* Variant CVE-2017-5754 relies on the fact that, on impacted\nmicroprocessors, during speculative execution of instruction\npermission faults, exception generation triggered by a faulting access\nis suppressed until the retirement of the whole instruction block. In\na combination with the fact that memory accesses may populate the\ncache even when the block is being dropped and never committed\n(executed), an unprivileged local attacker could use this flaw to read\nprivileged (kernel space) memory by conducting targeted cache\nside-channel attacks.

"The openSUSE Leap 42.2 kernel was updated to 4.4.56 fix various security issues and bugs.\n\nThe following security bugs were fixed :\n\n - CVE-2017-7184: The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel did not validate certain size data after an XFRM_MSG_NEWAE update, which allowed local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability, as demonstrated during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10 linux-image-* package 4.8.0.41.52 (bnc#1030573).\n\n - CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c (bnc#1028415).\n\n - CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline (bnc#1027565).\n\n - CVE-2017-6345: The LLC subsystem in the Linux kernel did not ensure that a certain destructor exists in required circumstances, which allowed local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls (bnc#1027190).\n\n - CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux kernel allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that made PACKET_FANOUT setsockopt system calls (bnc#1027189).\n\n - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly restrict association peel-off operations during certain wait states, which allowed local users to cause a denial of service (invalid unlock and double free) via a multithreaded application. NOTE: this vulnerability exists because of an incorrect fix for CVE-2017-5986 (bnc#1025235).\n\n - CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel allowed remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag (bnc#1026722).\n\n - CVE-2016-2117: The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly enables scatter/gather I/O, which allowed remote attackers to obtain sensitive information from kernel memory by reading packet data (bnc#968697).\n\n - CVE-2017-6347: The ip_cmsg_recv_checksum function in net/ipv4/ip_sockglue.c in the Linux kernel has incorrect expectations about skb data layout, which allowed local users to cause a denial of service (buffer over-read) or possibly have unspecified other impact via crafted system calls, as demonstrated by use of the MSG_MORE flag in conjunction with loopback UDP transmission (bnc#1027179).\n\n - CVE-2016-9191: The cgroup offline implementation in the Linux kernel mishandled certain drain operations, which allowed local users to cause a denial of service (system hang) by leveraging access to a container environment for executing a crafted application, as demonstrated by trinity (bnc#1008842).\n\n -

CVE-2017-7184: The xfrm_replay_verify_len function in\n net/xfrm/xfrm_user.c in the Linux kernel did not\n validate certain size data after an XFRM_MSG_NEWAE\n update, which allowed local users to obtain root\n privileges or cause a denial of service (heap-based\n out-of-bounds access) by leveraging the CAP_NET_ADMIN\n capability, as demonstrated during a Pwn2Own competition\n at CanSecWest 2017 for the Ubuntu 16.10 linux-image-*\n package 4.8.0.41.52 (bnc#1030573).\n\n - CVE-2016-10200: Race condition in the L2TPv3 IP\n Encapsulation feature in the Linux kernel allowed local\n users to gain privileges or cause a denial of service\n (use-after-free) by making multiple bind system calls\n without properly ascertaining whether a socket has the\n SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and\n net/l2tp/l2tp_ip6.c (bnc#1028415).\n\n - CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in\n the Linux kernel allowed local users to gain privileges\n or cause a denial of service (double free) by setting\n the HDLC line discipline (bnc#1027565).\n\n - CVE-2017-6345: The LLC subsystem in the Linux kernel did\n not ensure that a certain destructor exists in required\n circumstances, which allowed local users to cause a\n denial of service (BUG_ON) or possibly have unspecified\n other impact via crafted system calls (bnc#1027190).\n\n - CVE-2017-6346: Race condition in net/packet/af_packet.c\n in the Linux kernel allowed local users to cause a\n denial of service (use-after-free) or possibly have\n unspecified other impact via a multithreaded application\n that made PACKET_FANOUT setsockopt system calls\n (bnc#1027189).\n\n - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did\n not properly restrict association peel-off operations\n during certain wait states, which allowed local users to\n cause a denial of service (invalid unlock and double\n free) via a multithreaded application. NOTE: this\n vulnerability exists because of an incorrect fix for\n CVE-2017-5986 (bnc#1025235).\n\n - CVE-2017-6214: The tcp_splice_read function in\n net/ipv4/tcp.c in the Linux kernel allowed

Notable new/improved features :\n\n - Improved support for Hyper-V\n\n - Support for Matrox G200eH3\n\n - Support for tcp_westwood The following security bugs were fixed :\n\n - CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux kernel was too late in obtaining a certain lock and consequently could not ensure that disconnect function calls are safe, which allowed local users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003).\n\n - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bnc#1031579).\n\n - CVE-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440).\n\n - CVE-2017-7261: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not check for a zero value of certain levels data, which allowed local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031052).\n\n - CVE-2017-7187: The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel allowed 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 (bnc#1030213).\n\n - CVE-2017-7374: Use-after-free vulnerability in fs/crypto/ in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference) or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be freed prematurely (bnc#1032006).\n\n - CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c (bnc#1028415).\n\n - CVE-2017-6345: The LLC subsystem in the Linux kernel did not ensure that a certain destructor exists in required circumstances, which allowed local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls (bnc#1027190).\n\n - CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux kernel allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that made PACKET_FANOUT setsockopt system calls (bnc#1027189).\n\n - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly restrict association peel-off operations during certain wait states, which allowed local users to cause a denial of service (invalid unlock and double free) via a multithreaded application. NOTE: this vulnerability exists because of an incorrect fix for CVE-2017-5986 (bnc#1027066).\n\n - CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel allowed remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag (bnc#1026722).\n\n - CVE-2016-2117: The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly enables scatter/gather I/O, which allowed remote attackers to obtain sensitive information from kernel memory by reading packet data (bnc#968697).\n\n - CVE-2017-6347: The ip_cmsg_recv_checksum function in net/ipv4/ip_sockglue.c in the Linux kernel had incorrect expectations about skb data layout, which allowed local users to cause a denial of service (buffer over-read) or possibly have unspecified other impact via crafted system calls, as demonstrated by use of the MSG_MORE flag in conjunction with loopback UDP transmission (bnc#1027179).\n\n - CVE-2016-9191: The cgroup offline implementation in the Linux kernel mishandled certain drain operations, which allowed local users to cause a denial of service (system hang) by leveraging access to a container environment for executing a crafted application (bnc#1008842).\n\n - CVE-2017-2596: The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel improperly emulated the VMXON instruction, which allowed KVM L1 guest OS users to cause a denial of service (host OS memory consumption) by leveraging the mishandling of page references (bnc#1022785).\n\n - CVE-2017-6074: The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel mishandled DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allowed local users to obtain root privileges or cause a denial of service (double free) via an application that made an IPV6_RECVPKTINFO setsockopt system call (bnc#1026024).\n\nThe update package also includes non-security fixes.

There are three primary variants of the issue which differ in the way the speculative execution can be exploited.\n\nVariant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5715, Important, ARM)\n\nVariant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5753, Important, ARM)\n\nVariant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks.

running version MAIN 4.06, has kernel packages installed that are affected by multiple vulnerabilities:\n\n - The offset2lib patch as used by the Linux Kernel contains a vulnerability, if RLIMIT_STACK is set to RLIM_INFINITY and 1 Gigabyte of memory is allocated (the maximum under the 1/4 restriction) then the stack will be grown down to 0x80000000, and as the PIE binary is mapped above 0x80000000 the minimum distance between the end of the PIE binary's read-write segment and the start of the stack becomes small enough that the stack guard page can be jumped over by an attacker. This affects Linux Kernel version 4.11.5.\n This is a different issue than CVE-2017-1000370 and CVE-2017-1000365. This issue appears to be limited to i386 based systems. (CVE-2017-1000371)\n\n - The keyctl_read_key function in security/keys/keyctl.c in the Key Management subcomponent in the Linux kernel before 4.13.5 does not properly consider that a key may be possessed but negatively instantiated, which allows local users to cause a denial of service (OOPS and system crash) via a crafted KEYCTL_READ operation. (CVE-2017-12192)\n\n - The KEYS subsystem in the Linux kernel before 3.18 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving a NULL value for a certain match field, related to the keyring_search_iterator function in keyring.c. (CVE-2017-2647)\n\n - Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. (CVE-2018-12207)\n\n - Insufficient access control in subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Pentium(R) Processor J, N, Silver and Gold Series; Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series; Intel(R) Atom(R) Processor A and E3900 Series; Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100 Processor Families may allow an authenticated user to potentially enable denial of service via local access. (CVE-2019-0154)\n\n - Insufficient access control in a subsystem for Intel (R) processor graphics in 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Pentium(R) Processor J, N, Silver and Gold Series; Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series; Intel(R) Atom(R) Processor A and E3900 Series; Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and E-2200 Processor Families; Intel(R) Graphics Driver for Windows before 26.20.100.6813 (DCH) or 26.20.100.6812 and before 21.20.x.5077 (aka15.45.5077), i915 Linux Driver for Intel(R) Processor Graphics before versions 5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may allow an authenticated user to potentially enable escalation of privilege via local access. (CVE-2019-0155)\n\n - TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11135)\n\n - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after- free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests. (CVE-2019-11487)\n\n - An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system. (CVE-2019-14821)\n\n - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21. (CVE-2019-17055)\n\n - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)\n\n - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)\n\n - An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario. (CVE-2019-3900)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.\n This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service. (CVE-2020-10711)\n\n - A locking issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.\n drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.\n (CVE-2020-29661)\n\n - A flaw was found in the way memory resources were freed in the unix_stream_recvmsg function in the Linux kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by exhausting available memory. The highest threat from this vulnerability is to system availability.\n (CVE-2021-20265)\n\n - An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is adversely affected by the ability of an unprivileged user to craft Netlink messages. (CVE-2021-27364)\n\n - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a Netlink message.
