CVE-2026-49423 Remote DOS via uninitialized memory access in KTLS receive

When building the iovec array for a received TLS 1.2 CBC record, ktlsocftlscbcdecrypt incremented the iovec index for every mbuf in the chain, including mbufs that were skipped because they contained only TLS header bytes. This left uninitialized entries in the iovec array. The iovec array was...

ROS-20260713-73-0045

The vulnerability of the mbufgetbytes and mbufgetchars functions in PostgreSQL’s PgBouncer connection pool lies in integer overflow. Exploiting this vulnerability could allow a malicious actor to cause a service failure by sending a specially crafted authentication packet called SCRAM...

CVE-2026-4247 TCP: remotely exploitable DoS vector (mbuf leak)

When a challenge ACK is to be sent tcprespond constructs and sends the challenge ACK and consumes the mbuf that is passed in. When no challenge ACK should be sent the function returns and leaks the mbuf. If an attacker is either on path with an established TCP connection, or can themselves...

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...
