Security update for the Linux Kernel (important)






An update that solves 5 vulnerabilities and has 40 fixes is
now available.


The SUSE Linux Enterprise 15 SP3 Azure kernel was updated to receive
various security and bugfixes.

The following security bugs were fixed:

  • CVE-2021-3573: Fixed an UAF vulnerability in function that can allow
    attackers to corrupt kernel heaps and adopt further exploitations.
  • CVE-2021-0605: Fixed an out-of-bounds read which could lead to local
    information disclosure in the kernel with System execution privileges
    needed. (bsc#1187601)
  • CVE-2021-0512: Fixed a possible out-of-bounds write which could lead to
    local escalation of privilege with no additional execution privileges
    needed. (bsc#1187595)
  • CVE-2021-33624: Fixed a bug which allows unprivileged BPF program to
    leak the contents of arbitrary kernel memory (and therefore, of all
    physical memory) via a side-channel. (bsc#1187554)
  • CVE-2021-34693: Fixed a bug in net/can/bcm.c which could allow local
    users to obtain sensitive information from kernel stack memory because
    parts of a data structure are uninitialized. (bsc#1187452)
