Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2019-25161 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/display/dc/dce100/dce100_resource.c drivers/gpu/drm/amd/display/dc/dce110/dce110_resource.c drivers/gpu/drm/amd/display/dc/dce112/dce112_resource.c drivers/gpu/drm/amd/display/dc/dce120/dce120_resource.c drivers/gpu/drm/amd/display/dc/dcn10/dcn10_resource.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/60e1b411bf0fd9fda2d2de7f45dc3b1d9960b85e https://git.kernel.org/stable/c/104c307147ad379617472dd91a5bcb368d72bd6d
