Affected files ============== The file(s) affected by this issue are: samples/landlock/sandboxer.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/20fbf100f84b9aeb9c91421abe1927bc152bc32b https://git.kernel.org/stable/c/49b0d8bf05809df5f87e5c03e26d74bdfdab4571 https://git.kernel.org/stable/c/017196730299ccd6eed24bbfabed8af4ffd81530 https://git.kernel.org/stable/c/66b513b7c64a7290c1fbb88e657f7cece992e131
