Upgrade SLES:15.6 kernel-syms to version 6.4.0-150600.23.14.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES.
See How to fix? for SLES:15.6 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.
- asn1_encode_sequence() is not an internal function (located in lib/asn1_encode.c).
- Location is known, which makes the stack trace useless.
- 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.
