Affected files ============== The file(s) affected by this issue are: drivers/hwtracing/intel_th/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/859342220accd0d332864fafbf4e3d2d0492bc3f https://git.kernel.org/stable/c/a8f3b78b1f8e959d06801ae82149f140a75724e8 https://git.kernel.org/stable/c/9b5469573a274729bdb04b60a8d71f8d09940a31 https://git.kernel.org/stable/c/ed4d5ecb7d7fd80336afb2f9ac6685651a6aa32f https://git.kernel.org/stable/c/fae9da7d4c2ccad3792de03e3cac1fe2bfabb73d https://git.kernel.org/stable/c/086c28ab7c5699256aced0049aae9c42f1410313
