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)

local escalation of privilege with no additional execution privileges
needed. (bsc#1187595)

leak the contents of arbitrary kernel memory (and therefore, of all
physical memory) via a side-channel. (bsc#1187554)
