Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/display/dc/dml2/dml2_policy.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/945dc25eda88b5d6e30c9686dc619ab981c22d0e https://git.kernel.org/stable/c/4010efc8516899981cc3b57be2d4a2d5d9e50228 https://git.kernel.org/stable/c/0d5e5e8a0aa49ea2163abf128da3b509a6c58286
