How to fix?

Upgrade SLES:15.5 kernel-livepatch-5_14_21-150500_55_133-default to version 1-150500.11.3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150500_55_133-default package and not the kernel-livepatch-5_14_21-150500_55_133-default 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:

x86/kexec: Fix double-free of elf header buffer

After

b3e34a47f989 ("x86/kexec: fix memory leak of elf header buffer"),

freeing image->elf_headers in the error path of crash_load_segments() is not needed because kimage_file_post_load_cleanup() will take care of that later. And not clearing it could result in a double-free.

Drop the superfluous vfree() call at the error path of crash_load_segments().
