Affected files ============== The file(s) affected by this issue are: net/ipv4/tcp_output.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/9b5dc7ad6da1373d3c60d4b869d688f996e5d219 https://git.kernel.org/stable/c/44768749980d53bc01980d9c060f736808d11af0 https://git.kernel.org/stable/c/96900fa61777402eb5056269d8000aace33a8b6c https://git.kernel.org/stable/c/b04817c94fbd285a967d9b830b274fe9998c9c0b https://git.kernel.org/stable/c/d452ce36f2d4c402fa3f5275c9677f80166e7fc6 https://git.kernel.org/stable/c/f524c3e7f6cdad66b3b6a912cef47b656f8b0de3 https://git.kernel.org/stable/c/fa5fb2cf9393db898772db8cb897ed5fd265eb78 https://git.kernel.org/stable/c/92c0aa4175474483d6cf373314343d4e624e882a
