This triggers\nthe WARN_ON() at nf_nat_setup_info() and if panic_on_warn isn't set,\nthen IPS_SRC_NAT_DONE is set without adding nat_bysource and conntrack\ncleanup tries to unlink an uninitialized hlist node.\n\nFix this by checking that NAT manipulation type is correct before\ncalling nf_nat_setup_info(). In addition, if the WARN_ON is hit, return\nNF_DROP instead of continuing with the processing to avoid similar\nsituations in the future.","score":null,"severity":"unknown","published":"2026-10-18T15:48:33.555Z","modified":"2026-10-30T12:39:51.633Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"0fabd2aa199faeb8754aee94658f2c48ccb2c8c3","status":"affected","lessThan":"ce7b41f0e4b5db0580d0a2059a0c9e672b461b5e","versionType":"git"},{"version":"0fabd2aa199faeb8754aee94658f2c48ccb2c8c3","status":"affected","lessThan":"752492947be3123ea6c689e2f93ae04ecd675d42","versionType":"git"},{"version":"0fabd2aa199faeb8754aee94658f2c48ccb2c8c3","status":"affected","lessThan":"ea777dc90ab37e64fa4b92f6fcf3b5edcef5e058","versionType":"git"},{"version":"0fabd2aa199faeb8754aee94658f2c48ccb2c8c3","status":"affected","lessThan":"f6143ae109df56d51d5536e813deb19eee7a6205","versionType":"git"},{"version":"0fabd2aa199faeb8754aee94658f2c48ccb2c8c3","status":"affected","lessThan":"58108f05b0502448f6bb612ee2eccc63bd6449cb","versionType":"git"},{"version":"0fabd2aa199faeb8754aee94658f2c48ccb2c8c3","status":"affected","lessThan":"16d464013ec2267b00a83f4bfbb97b3ecc63bfa7","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98793"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"6.1","status":"affected"},{"version":"0","status":"unaffected","lessThan":"6.1","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-2026-98793"}],"remediation":[],"references":["https://git.kernel.org/stable/c/ce7b41f0e4b5db0580d0a2059a0c9e672b461b5e","https://git.kernel.org/stable/c/752492947be3123ea6c689e2f93ae04ecd675d42","https://git.kernel.org/stable/c/ea777dc90ab37e64fa4b92f6fcf3b5edcef5e058","https://git.kernel.org/stable/c/f6143ae109df56d51d5536e813deb19eee7a6205","https://git.kernel.org/stable/c/58108f05b0502448f6bb612ee2eccc63bd6449cb","https://git.kernel.org/stable/c/16d464013ec2267b00a83f4bfbb97b3ecc63bfa7"],"sources":[{"name":"CVE","id":"CVE-2026-98793","modified":"2026-10-30T12:39:51.633Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98793"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T13:09:17.480Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T02:45:32.518Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
