Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/xe/xe_guc_relay.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/499be4b5d64209e9f18c9442f9fbeef7155ae900 https://git.kernel.org/stable/c/adc7dda728ca3e340a413e3bbc10cf159e1866a4 https://git.kernel.org/stable/c/a4208d8032abd7f591581994f31e23b80b8fe659 https://git.kernel.org/stable/c/ed8b0d731892c68b41ecbd27c952af284816dec1
