Affected files ============== The file(s) affected by this issue are: drivers/media/platform/qcom/venus/hfi_venus.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/4e95233af57715d81830fe82b408c633edff59f4 https://git.kernel.org/stable/c/5af611c70fb889d46d2f654b8996746e59556750 https://git.kernel.org/stable/c/530f623f56a6680792499a8404083e17f8ec51f4 https://git.kernel.org/stable/c/a062d8de0be5525ec8c52f070acf7607ec8cbfe4 https://git.kernel.org/stable/c/d78a8388a27b265fcb2b8d064f088168ac9356b0 https://git.kernel.org/stable/c/f4b211714bcc70effa60c34d9fa613d182e3ef1e
