Affected files ============== The file(s) affected by this issue are: drivers/accel/ivpu/ivpu_gem.h drivers/accel/ivpu/ivpu_ipc.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/5419be345f32222750e006b85b7f9bae1a285c8e https://git.kernel.org/stable/c/43c68f52aecd519eb682fa09d57ae52c896f860f https://git.kernel.org/stable/c/29f82a2280e170429370e7a842cde4e70ead8547 https://git.kernel.org/stable/c/3837c3f29fbc3b8c12bebf5c62741e2befe3482a
