Doc Text: |
A vulnerability found in the Linux kernel’s bpf subsystem, involving a frequent warning (splat) in pskb_may_pull during syzkaller builds (CONFIG_DEBUG_NET=y), has been resolved. The warning, caused by nonsensical BPF programs generated by fuzzers, was suppressed as it provided no useful information. For non-debug builds (CONFIG_DEBUG_NET=n), the check is unnecessary, as pskb_may_pull handles errors without triggering warnings.
