Upgrade SLES:15.5 kernel-source-azure to version 5.14.21-150500.33.60.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source-azure package and not the kernel-source-azure package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

KEYS: trusted: Do not use WARN when encode fails

When asn1_encode_sequence() fails, WARN is not the correct solution.

  1. asn1_encode_sequence() is not an internal function (located in lib/asn1_encode.c).
  2. Location is known, which makes the stack trace useless.
  3. Results a crash if panic_on_warn is set.

It is also noteworthy that the use of WARN is undocumented, and it should be avoided unless there is a carefully considered rationale to use it.

Replace WARN with pr_err, and print the return value instead, which is only useful piece of information.
