{"schema":"threatline.record/2","record":{"id":"CVE-2026-98614","aliases":[],"summary":"sctp: avoid livelock while updating retransmit path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: avoid livelock while updating retransmit path\n\nsctp_assoc_update_retran_path() can loop forever when every remaining\ntransport, including retran_path, is SCTP_UNCONFIRMED: the state check\nruns before the wraparound test, so the loop cannot observe that it has\ncompleted a full pass.\n\nFix this by considering a transport only when it is not UNCONFIRMED,\nthen checking whether the walk has returned to retran_path. This makes\nthe full-pass termination independent of the transport state while\npreserving the existing fallback selection semantics.\n\nAlso restore the NULL guard around the retran_path assignment. In the\nall-UNCONFIRMED case there is no eligible replacement transport, and\ninstalling NULL would leave later retransmit-path users and the debug\nprint with a NULL path.","categories":["Operating
