CVE-2026-58090
The SOCKSTREAM receive path in the unix socket implementation failed to fully detach control messages from the socket buffer before processing them. Some error paths would free those messages, leaving freed data mbufs in the receive socket buffer. An unprivileged local user can exploit this...

CVE-2026-4247
CVE-2026-4247 affects FreeBSD TCP implementations (bases: 14.x, 15.x/releng) where, when a challenge ACK should be sent, tcp_respond() consumes the mbuf and can leak the mbuf if no ACK is sent. An attacker on-path or able to establish a TCP connection can craft packets that trigger a challenge AC...
