Affected files ============== The file(s) affected by this issue are: net/9p/trans_xen.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/692eb06703afc3e24d889d77e94a0e20229f6a4a https://git.kernel.org/stable/c/d74b4b297097bd361b8a9abfde9b521ff464ea9c https://git.kernel.org/stable/c/7f5a2ed5c1810661e6b03f5a4ebf17682cdea850 https://git.kernel.org/stable/c/4950408793b118cb8075bcee1f033b543fb719fa https://git.kernel.org/stable/c/b9e26059664bd9ebc64a0e8f5216266fc9f84265 https://git.kernel.org/stable/c/2bb3ee1bf237557daea1d58007d2e1d4a6502ccf https://git.kernel.org/stable/c/d888f5f5d76b2722c267e6bdf51d445d60647b7b https://git.kernel.org/stable/c/530bc9f03a102fac95b07cda513bfc16ff69e0ee https://git.kernel.org/stable/c/e43c608f40c065b30964f0a806348062991b802d
