CVE-2026-80637

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

netfilter: synproxy: fix unaligned memory access in timestamp adjustment

Use get_unaligned_be32() and put_unaligned_be32() 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 tcp_parse_options() and synproxy_parse_options().
