Kerentanan Use After Free pada freebsd. Skor CVSS 3.1 7.8 (High) menurut CISA ADP.

Deskripsi (NVD)

The SOCK_STREAM 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 use-after-free to escalate privileges.
