## Description:

This update for the Linux Kernel 5.3.18-150200_24_142 fixes several issues.

The following security issues were fixed:

  * CVE-2023-4921: Fixed a use-after-free vulnerability in the QFQ network
    scheduler which could be exploited to achieve local privilege escalation
    (bsc#1215300).
  * CVE-2023-39198: Fixed a race condition leading to a use-after-free in
    qxl_mode_dumb_create() (bsc#1217116).
  * CVE-2023-51780: Fixed a use-after-free in do_vcc_ioctl in net/atm/ioctl.c,
    because of a vcc_recvmsg race condition (bsc#1218733).
