Summary
Security update for the Linux Kernel
Details

The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2021-3348: Fixed a use-after-free in nbdaddsocket() that could be triggered by local attackers (with access to the nbd device) via an I/O request (bnc#1181504).
  • CVE-2021-3347: A use-after-free was discovered in the PI futexes during fault handling, allowing local users to execute code in the kernel (bnc#1181349).
  • CVE-2020-27835: A use-after-free in the infiniband hfi1 driver was found, specifically in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system (bnc#1179878).
