Affected files ============== The file(s) affected by this issue are: drivers/crypto/bcm/spu2.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/c256b616067bfd6d274c679c06986b78d2402434 https://git.kernel.org/stable/c/e719c8991c161977a67197775067ab456b518c7b https://git.kernel.org/stable/c/ebed0d666fa709bae9e8cafa8ec6e7ebd1d318c6 https://git.kernel.org/stable/c/c69a1e4b419c2c466dd8c5602bdebadc353973dd https://git.kernel.org/stable/c/49833a8da6407e7e9b532cc4054fdbcaf78f5fdd https://git.kernel.org/stable/c/d0f14ae223c2421b334c1f1a9e48f1e809aee3a0 https://git.kernel.org/stable/c/c0082ee420639a97e40cae66778b02b341b005e5 https://git.kernel.org/stable/c/3b7a40740f04e2f27114dfd6225c5e721dda9d57 https://git.kernel.org/stable/c/2b3460cbf454c6b03d7429e9ffc4fe09322eb1a9
