Summary
Security update for the Linux Kernel (Live Patch 30 for SLE 12 SP2)
Details

This update for the Linux Kernel 4.4.121-92_114 fixes several issues.

The following security issues were fixed:

  • CVE-2019-11487: The Linux kernel allowed 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/pipefs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests (bsc#1133191).
  • CVE-2018-5390: Linux kernel could be forced to make very expensive calls to tcpcollapseofoqueue() and tcppruneofoqueue() for every incoming packet which can lead to a denial of service (bsc#1102682).
