Affected files ============== The file(s) affected by this issue are: arch/um/drivers/vector_kern.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/5c49fb5ad01104acc584405572abf6616d45148e https://git.kernel.org/stable/c/6480c3a12755bf85d6738ab60967e89b809c701a https://git.kernel.org/stable/c/f2b9c4544e3bd60f353732291300097b0e8d8454 https://git.kernel.org/stable/c/276a7298af6a801e9a865282605a79303365ec66 https://git.kernel.org/stable/c/c8583b4655aab44a9796b5c4a681ddcc6fe2f0d0 https://git.kernel.org/stable/c/634a9c139cc1362f6a9cc6cbfe442dbb60ff9f3f https://git.kernel.org/stable/c/8f88c73afe481f93d40801596927e8c0047b6d96
