CVE-2026-4247
A memory leak vulnerability exists in the FreeBSD TCP stack within the tcp_respond() function. When the system decides not to send a challenge ACK, the function returns without consuming the passed mbuf , leading to a memory leak. An attacker who can establish a TCP connection or is on-path can c...
