Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/amdkfd/kfd_process_queue_manager.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/781110700ada22168fbb490dd61432d23a17a5b4 https://git.kernel.org/stable/c/529c985da1b277b36dc99aad660f96dc70f3c467 https://git.kernel.org/stable/c/b2b7742c465c8e3b36dc325a48abb4b9f2aaa38b https://git.kernel.org/stable/c/2ce75a0b7e1bfddbcb9bc8aeb2e5e7fa99971acf
