CVSS N/A
Overview
In the Linux kernel, the following vulnerability has been resolved:
s390/bpf: Fix bpf_arch_text_poke() with new_addr == NULL again
Commit 7ded842b356d ("s390/bpf: Fix bpf_plt pointer arithmetic") has
accidentally removed the critical piece of commit c730fce7c70c
("s390/bpf: Fix bpf_arch_text_poke() with new_addr == NULL"), causing
intermittent kernel panics in e.g. perf's on_switch() prog to reappear.
Restore the fix and add a comment.
