Affected files ============== The file(s) affected by this issue are: drivers/iommu/fsl_pamu.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/c93983230562883e0b5f122040efbb3d478c36d4 https://git.kernel.org/stable/c/a305d0e4d0ce3166e31d7dbcb4c98b09cad6d49a https://git.kernel.org/stable/c/9fbccdf2fefa3944dd8ba8c6a808b387787f3917 https://git.kernel.org/stable/c/17fd440594961c5e2ea0f58591bc1bdba0629c75 https://git.kernel.org/stable/c/0d240ac0e4c35d3f64fc782c11433138c1bd016e https://git.kernel.org/stable/c/e42b543d08052c3b223bcfb48f05cbaf0b767f86 https://git.kernel.org/stable/c/9238b687fd62cde14c6e2e8576a40e4246de7ebe https://git.kernel.org/stable/c/de7eb55009796687fc0a1670e0b944fa8ed54e9b https://git.kernel.org/stable/c/73f5fc5f884ad0c5f7d57f66303af64f9f002526
