   An update that fixes two vulnerabilities is now available.

Description:

   This update for the Linux Kernel 4.4.180-94_138 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)
