A flaw was found in the Linux kernel's Stream Control Transmission Protocol (SCTP) subsystem. An attacker could exploit this vulnerability to cause a Denial of Service (DoS) by triggering an infinite loop during retransmission path selection. When all candidate network paths are in an unconfirmed state, the kernel fails to recognize the completion of its search loop, resulting in system livelock and CPU starvation.
kernel: sctp: avoid livelock while updating retransmit path — rated Important by Red Hat. Released 2026-10-18, updated 2026-10-21.
