Affected files ============== The file(s) affected by this issue are: net/tipc/bearer.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/f07670871f4d19e613740eebe210e7e9ea535973 https://git.kernel.org/stable/c/8b91d0dfc839e67708c905648cd0e7507a2263e5 https://git.kernel.org/stable/c/b8fac8e321044a9ac50f7185b4e9d91a7745e4b0 https://git.kernel.org/stable/c/92a930fcf4250fe961f6238b99af0bc405799f39 https://git.kernel.org/stable/c/292be63c382ce20673ee61dff1ee9ed4a3dcaae7 https://git.kernel.org/stable/c/3af15272cde28fe5c8489174b8624e232c1775ec https://git.kernel.org/stable/c/7f36f798f89bf32c0164049cb0e3fd1af613d0bb
