Security update for the Linux Kernel (important)

tcp source port
use after free
nfc device





An update that solves 7 vulnerabilities and has 10 fixes is
now available.


The SUSE Linux Enterprise 15 SP3 kernel was updated.

The following security bugs were fixed:

  • CVE-2022-1012: Fixed a small table perturb size in the TCP source port
    generation algorithm which could leads to information leak.
  • CVE-2022-20141: Fixed an use after free due to improper locking. This
    bug could lead to local escalation of privilege when opening and closing
    inet sockets with no additional execution privileges needed.
  • CVE-2022-32250: Fixed an use-after-free bug in the netfilter subsystem.
    This flaw allowed a local attacker with user access to cause a privilege
    escalation issue. (bnc#1200015)
  • CVE-2022-1975: Fixed a sleep-in-atomic bug that allows attacker to crash
    linux kernel by simulating nfc device from user-space. (bsc#1200143)
  • CVE-2022-1974: Fixed an use-after-free that could causes kernel crash by
    simulating an nfc device from user-space. (bsc#1200144)
  • CVE-2020-26541: Enforce the secure boot forbidden signature database
    (aka dbx) protection mechanism. (bnc#1177282)
