Description:

This update for the Linux Kernel 4.12.14-122_23 fixes several issues.

The following security issues were fixed:

  • CVE-2020-36322: Fixed an issue inside the FUSE filesystem implementation where fuse_do_getattr() calls make_bad_inode() in inappropriate situations, could have caused a system crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as CVE-2021-28950 (bsc#1184952).
  • CVE-2021-29154: Fixed BPF JIT compilers that allowed to execute arbitrary code within the kernel context (bsc#1184710)
  • Fix system crash on kernfs_kill_sb() as a sysfs superblock's kernfs_super_info node list was NULL (bsc#1183452).
