Affected files ============== The file(s) affected by this issue are: lib/fortify_kunit.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7880dbf4eafe22a6a41a42e774f1122c814ed02d https://git.kernel.org/stable/c/42d21c9727028fe7ee392223ba127484b1b8677e https://git.kernel.org/stable/c/03758d5a0932016b6d5f5bfbca580177e6bc937a https://git.kernel.org/stable/c/998b18072ceb0613629c256b409f4d299829c7ec
