24 Dec 2025 — In the Linux kernel, the following vulnerability has been resolved: bpf: drop unnecessary user-triggerable WARN_ONCE in verifierl log It's trivial for user to trigger "verifier log line truncated" warning, as verifier has a fixed-sized buffer of 1024 bytes (as of now), and there are at least two pieces of user-provided information that can be output through this buffer, and both can be arbitrarily sized by user: - BTF names; - BTF.ext source code lines strings. Verifier log buffer should be properly sized f... • https://git.kernel.org/stable/c/40c88c429a598006f91ad7a2b89856cd50b3a008 •
