This update for the Linux Kernel 3.12.74-60_64_107 fixes several issues.
The following security issues were fixed:
- CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network (bsc#1136446).
- CVE-2019-11477: A sequence of SACKs may have been crafted by a remote attacker such that one can trigger an integer overflow, leading to a kernel panic. (bsc#1137586).
- CVE-2019-11478: It was possible to send a crafted sequence of SACKs which would fragment the TCP retransmission queue. A remote attacker may have been able to
Security update for the Linux Kernel (Live Patch 34 for SLE 12)
This update for the Linux Kernel 3.12.61-52_128 fixes several issues.
The following security issues were fixed:
- CVE-2019-9213: Expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bsc#1128378).
- CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124734).
- CVE-2018-5391: The Linux kernel was vulnerable to a denial of service a
Security update for the Linux Kernel (Live Patch 35 for SLE 12)
This update for the Linux Kernel 3.12.61-52_133 fixes one issue.
The following security issue was fixed:
- CVE-2018-16884: A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time could make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user could cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bsc#1119947).
Security update for the Linux Kernel (Live Patch 38 for SLE 12)
This update for the Linux Kernel 3.12.61-52_146 fixes one issue.
The following security issue was fixed:
- CVE-2018-9568: Prevent possible memory corruption due to type confusion in sk_clone_lock. This could lead to local privilege escalation (bsc#1118319).
Security update for the Linux Kernel (Live Patch 31 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_104 fixes one issue.
The following security issue was fixed:
- CVE-2018-18386: The drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bsc#1112039).
Security update for the Linux Kernel (Live Patch 29 for SLE 12)
This update for the Linux Kernel 3.12.61-52_106 fixes several issues.
The following security issues were fixed:
- CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bsc#1110233).
- CVE-2018-14634: An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable (bsc#1108963).
- CVE-2018-146
Security update for the Linux Kernel (Live Patch 29 for SLE 12)
This update for the Linux Kernel 3.12.61-52_106 fixes several issues.
The following security issues were fixed:
- CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming TCP packet which can lead to a denial of service (bsc#1102682).
- CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which lead to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(), allowing a malicious local attacker to use this for privilege escalation (bsc#1105323).
Security update for the Linux Kernel (Live Patch 24 for SLE 12 SP2)
This update for the Linux Kernel 4.4.121-92_92 fixes one issue.
The following security issue was fixed:
- CVE-2018-10853: A KVM guest userspace to guest kernel write was fixed, which could be used by guest users to crash the guest kernel (bsc#1097108).
The SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had an integer overflow via a large relative timeout because ktime_add_safe is not used (bnc#1099924).
- CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group own
