AF_PACKET sends then retain the\nskb and its socket write-memory charge.\n\nA TX-enabled, link-down port keeps the broadcast transmit op installed.\nCarrier can stay up through a second link-up, TX-disabled port or be\nforced on by userspace. Free the original skb on the no-port path while\nleaving the existing drop accounting intact.\n\nDiscovered by Sashiko during review of previous commit.","score":null,"severity":"unknown","published":"2026-10-23T12:21:13.509Z","modified":"2026-11-10T18:15:22.929Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"5fc889911a99043a97da1daa0d010ad72cbc3042","status":"affected","lessThan":"aec1d35d76ad883bae83c24707010115f38d02ac","versionType":"git"},{"version":"5fc889911a99043a97da1daa0d010ad72cbc3042","status":"affected","lessThan":"961563117626f4681623077ec0cfd86f86da0d49","versionType":"git"},{"version":"5fc889911a99043a97da1daa0d010ad72cbc3042","status":"affected","lessThan":"f34b1bcac4581a5bd3daf9eff90f175e736b54aa","versionType":"git"},{"version":"5fc889911a99043a97da1daa0d010ad72cbc3042","status":"affected","lessThan":"489114c9ecae44e523361a4b3e610ee5ebd9189c","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-99026"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"3.6","status":"affected"},{"version":"0","status":"unaffected","lessThan":"3.6","versionType":"semver"},{"version":"6.12.117","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.57","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.11","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-2026-99026"}],"remediation":[],"references":["https://git.kernel.org/stable/c/aec1d35d76ad883bae83c24707010115f38d02ac","https://git.kernel.org/stable/c/961563117626f4681623077ec0cfd86f86da0d49","https://git.kernel.org/stable/c/f34b1bcac4581a5bd3daf9eff90f175e736b54aa","https://git.kernel.org/stable/c/489114c9ecae44e523361a4b3e610ee5ebd9189c"],"sources":[{"name":"CVE","id":"CVE-2026-99026","modified":"2026-11-10T18:15:22.929Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-99026"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-11-10T18:25:33.869Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T22:15:32.260Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
