CVE-2026-46168

The CVE concerns the Linux kernel, specifically mptcp: fix scheduling with atomic in timestamp sockopt. The issue arises from using lock_sock_fast() (an atomic-context lock) around sock_set_timestamp() and sock_set_timestamping(), since these helpers can sleep, making scheduling unsafe. The remed...
