Also, add more checks for the length of the inner headers. The Linux kernel CVE team has assigned CVE-2026-72319 to this issue.

Affected files ============== The file(s) affected by this issue are: net/netfilter/ipvs/ip_vs_core.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/19657b3a17b774ae4e2f2635b5ae8638c9344a40 https://git.kernel.org/stable/c/dac813101914c21219ac221a60a31a11bc90e7ec https://git.kernel.org/stable/c/dd22f74a09e25ca298ced0a3763ef353242cb78d https://git.kernel.org/stable/c/9bc9b95aee2b2e3f1301a16a67ee504960402875 https://git.kernel.org/stable/c/a735f9964a3d9ed97daf9b08507f8b5bcafe6326 https://git.kernel.org/stable/c/8f48cfe657409fb5c7ba0521b14da6d47546d9cf https://git.kernel.org/stable/c/92185d6f7819bc558939ae83de7b1abe90e3b5c2 https://git.kernel.org/stable/c/3f7a535ff0fa627a0132803e4c2f903ceffcbc1c
