CVE-2026-74282

In the Linux kernel vulnerability CVE-2026-74282, the TIPC stack allows an oversized CONN_ACK to cause snt_unacked to underflow. The root cause is tipc_sk_conn_proto_rcv() subtracting the peer-supplied ack count from an unsigned 16-bit snt_unacked without ensuring it does not exceed the outstandi...
