CVE-2026-46168

The CVE-2026-46168 issue affects the Linux kernel's multipath TCP (mptcp) scheduling around timestamp sockopts. The root cause is using lock_sock_fast() (atomic context) around sock_set_timestamp() and sock_set_timestamping(), which can sleep and cause atomic-context issues. The published fixes r...
