Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/i915/i915_pci.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/2239e6b49d33bb38817d69b4f0bf7d5cbde2ec68 https://git.kernel.org/stable/c/4a0236fe97732e31cb4a6dcb433642f9e3ef9a56 https://git.kernel.org/stable/c/e351cb2d373f6f1d4f1eb7c9f30dc058c69c89f8 https://git.kernel.org/stable/c/18b3433f10ee9c69e3252046028aa2be421f2d4d https://git.kernel.org/stable/c/84829e324a396668ceafb14723293b2863a74dcf https://git.kernel.org/stable/c/3785d40831ba5601296283e0197e10e089392757
