An\nout-of-the-blue ABORT can then be processed from the socket backlog and\nunlink the association. If a concurrent shutdown(fd, SHUT_RD) sets\nRCV_SHUTDOWN, the waiter breaks with err == 0 before checking\nasoc->base.dead. Its final sctp_association_put() can then free the\nassociation, leaving sctp_sendmsg_to_asoc() to continue with a dangling\npointer.\n\nCheck RCV_SHUTDOWN along with the wait error in sctp_sendmsg_to_asoc()\nbefore using the association again. The check only accesses the socket,\nso it needs no additional association reference. Return the existing\n-ESRCH so that sctp_sendmsg() skips freeing a new association that may\nalready have been destroyed.\n\nKeep sctp_wait_for_connect() unchanged to preserve its behavior for the\nconnect() caller.","score":null,"severity":"unknown","published":"2026-10-18T15:50:34.714Z","modified":"2026-10-30T12:40:09.817Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"668c9beb9020d5834ee9e43c208190a07d2b1928","status":"affected","lessThan":"7f798168c54455559da0f7a377a23ab7019fec35","versionType":"git"},{"version":"668c9beb9020d5834ee9e43c208190a07d2b1928","status":"affected","lessThan":"fe5a23c76fc48b711eb7d6f3462c994e34da36f9","versionType":"git"},{"version":"668c9beb9020d5834ee9e43c208190a07d2b1928","status":"affected","lessThan":"1e7cd89975fa3b11ebd7e1bbb4648a71c0e0e2d4","versionType":"git"},{"version":"668c9beb9020d5834ee9e43c208190a07d2b1928","status":"affected","lessThan":"1bef1944ef15a40797305bf916827b04df6307ca","versionType":"git"},{"version":"668c9beb9020d5834ee9e43c208190a07d2b1928","status":"affected","lessThan":"e8f972b1759d26bbefe4c524caae1ed7c8a593bd","versionType":"git"},{"version":"668c9beb9020d5834ee9e43c208190a07d2b1928","status":"affected","lessThan":"e701345d886e831fb593a0870d69c8c5de6fc938","versionType":"git"},{"version":"668c9beb9020d5834ee9e43c208190a07d2b1928","status":"affected","lessThan":"222c41e0f50f1d5028be9baf0e1dcfc0bfa7f669","versionType":"git"},{"version":"668c9beb9020d5834ee9e43c208190a07d2b1928","status":"affected","lessThan":"4f1da630d13de0370e2f6361f961f1c8b384af1c","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98846"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"4.16","status":"affected"},{"version":"0","status":"unaffected","lessThan":"4.16","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.113","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.56","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.10","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98846"}],"remediation":[],"references":["https://git.kernel.org/stable/c/7f798168c54455559da0f7a377a23ab7019fec35","https://git.kernel.org/stable/c/fe5a23c76fc48b711eb7d6f3462c994e34da36f9","https://git.kernel.org/stable/c/1e7cd89975fa3b11ebd7e1bbb4648a71c0e0e2d4","https://git.kernel.org/stable/c/1bef1944ef15a40797305bf916827b04df6307ca","https://git.kernel.org/stable/c/e8f972b1759d26bbefe4c524caae1ed7c8a593bd","https://git.kernel.org/stable/c/e701345d886e831fb593a0870d69c8c5de6fc938","https://git.kernel.org/stable/c/222c41e0f50f1d5028be9baf0e1dcfc0bfa7f669","https://git.kernel.org/stable/c/4f1da630d13de0370e2f6361f961f1c8b384af1c"],"sources":[{"name":"CVE","id":"CVE-2026-98846","modified":"2026-10-30T12:40:09.817Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98846"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T13:09:43.988Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T23:30:30.969Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
