CVE-2026-80637

In the Linux kernel, the following vulnerability has been resolved:

netfilter: synproxy: fix unaligned memory access in timestamp adjustment

Use getunalignedbe32() and putunalignedbe32() to safely read and write the timestamp fields. This prevents performance degradation due to unaligned memory access or even a crash on strict alignment architectures.

This follows the implementation of timestamp parsing in the networking stack at tcpparseoptions() and synproxyparseoptions().
