gpp_maybe Security update for the linux kernel (live patch 13 for sle 12 sp2)
SUSE-SLE-SAP-12-SP2-2018-1651

This update for the Linux Kernel 4.4.74-92_38 fixes several issues. The following security issues were fixed: - CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system (bsc#1099306). - CVE-2017-18344: The timer_create syscall implementation in kernel/time/posix-timers.c didn't properly validate the sigevent->sigev_notify field, which lead to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allowed userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE) (bsc#1103203). before 4.14.8 - CVE-2017-11600: net/xfrm/xfrm_policy.c did not ensure that the dir value of xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allowed local users to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink message (bsc#1096564) - CVE-2018-10853: A flaw was found in kvm. In which certain instructions such as sgdt/sidt call segmented_write_std didn't propagate access correctly. As such, during userspace induced exception, the guest can incorrectly assume that the exception happened in the kernel and panic. (bsc#1097108).
