⚠️ Vulnerability Report

CVE-2026-74469

HIGH CVSS 8.8 CVSS 3.1 📌 Received

CVE-2026-74469 - sctp: prevent peer transport count overflow

In the Linux kernel, the following vulnerability has been resolved:

sctp: prevent peer transport count overflow

sctp_assoc_add_peer() increments the association's 16-bit transport_count

for every new unique peer. Adding the 65,536th transport wraps the count to

zero.

SCTP sock_diag uses transport_count to reserve the INET_DIAG_PEERS payload,

then copies one sockaddr_storage for every entry in transport_addr_list.

After the wrap, a diagnostic dump reserves an empty payload and writes

8 MiB of peer addresses past the skb tail.

Reject a new unique peer when transport_count has reached U16_MAX. Perform

the check after the existing-peer lookup so a duplicate address continues

to return its existing transport at the limit.
