How to fix?

Upgrade SLES:15.6 kernel-azure-devel to version 6.4.0-150600.8.11.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-azure-devel package and not the kernel-azure-devel 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:

ipv6: sr: fix memleak in seg6_hmac_init_algo

seg6_hmac_init_algo returns without cleaning up the previous allocations if one fails, so it's going to leak all that memory and the crypto tfms.

Update seg6_hmac_exit to only free the memory when allocated, so we can reuse the code directly.
