How to fix?

Upgrade SLES:15.7 kernel-default-base to version 6.4.0-150700.53.81.1.150700.17.45.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-base package and not the kernel-default-base package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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

s390/bpf: Zero-extend bpf prog return values and kfunc arguments

s390x ABI requires callers to zero-extend unsigned arguments and sign-extend signed arguments, and callees to zero-extend unsigned return values and sign-extend signed return values.

s390 BPF JIT currently implements only sign extension. Fix this omission and implement zero extension too.
