Affected files ============== The file(s) affected by this issue are: drivers/usb/host/ehci-ppc-of.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/b9c4a480cb0ada07154debf681454cbb55e30b59 https://git.kernel.org/stable/c/038453b17fe30ea38f0f3c916e2ae2b7f8cef84e https://git.kernel.org/stable/c/8cbc3870ff356366842af3228dd8e7bc278e5edd https://git.kernel.org/stable/c/585d22a5624ef2b540c337665c72fea8cd33db50 https://git.kernel.org/stable/c/c0a4b454486b23bb4d94ce49f490830ecc354040 https://git.kernel.org/stable/c/8e51a512c1079109bec4c80915e647692d583e79 https://git.kernel.org/stable/c/3a50c917c67dd0bc39c14de4a8b75a1d50fdce66 https://git.kernel.org/stable/c/b5c5b13cb45e2c88181308186b0001992cb41954
