abort break signalling on hangup","titleSource":"Linux","descriptionSource":"Linux","description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntty: abort break signalling on hangup\n\nThe break ioctls can race with hangup and end up calling into a tty\ndriver for a device that is already gone or powered down.\n\nDrivers must handle this race, but TCSBRK and TCSBRKP should still be\naborted to avoid calling back into the driver after a user-controlled\ntimeout (possibly even after the tty has been reopened).\n\nNote that drivers should disable any break state on shutdown so just\nreturn on hangup (calling break_ctl() again is racy and will most likely\nfail for drivers handling the race).","score":null,"severity":"unknown","published":"2026-10-18T15:47:36.026Z","modified":"2026-10-30T12:39:21.567Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"f34d7a5b7010b82fe97da95496b9971435530062","status":"affected","lessThan":"70fa2bec352d9f949b882af3c380b916e4a29a43","versionType":"git"},{"version":"f34d7a5b7010b82fe97da95496b9971435530062","status":"affected","lessThan":"8224d25534580d07925607bbd617daf9c8de26c3","versionType":"git"},{"version":"f34d7a5b7010b82fe97da95496b9971435530062","status":"affected","lessThan":"8a0f0f9ef41cb80de4d5da4ae146df3075463f6b","versionType":"git"},{"version":"f34d7a5b7010b82fe97da95496b9971435530062","status":"affected","lessThan":"6c9c9367351a461d62e5c0a39bffdcfbb40f068b","versionType":"git"},{"version":"f34d7a5b7010b82fe97da95496b9971435530062","status":"affected","lessThan":"3bc82999fb85cecc7eb6ec1755ee7d698aa1e783","versionType":"git"},{"version":"f34d7a5b7010b82fe97da95496b9971435530062","status":"affected","lessThan":"94af6cd832e9b4ce39a8fb59144a8f09ab56fd35","versionType":"git"},{"version":"f34d7a5b7010b82fe97da95496b9971435530062","status":"affected","lessThan":"c8ccd3b2013daaf77b98f8a6724fcf4d2c5c52d6","versionType":"git"},{"version":"f34d7a5b7010b82fe97da95496b9971435530062","status":"affected","lessThan":"845a2737e0f5ffe5ca8d38de556012b0c9472cdd","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98751"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"2.6.26","status":"affected"},{"version":"0","status":"unaffected","lessThan":"2.6.26","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-2026-98751"}],"remediation":[],"references":["https://git.kernel.org/stable/c/70fa2bec352d9f949b882af3c380b916e4a29a43","https://git.kernel.org/stable/c/8224d25534580d07925607bbd617daf9c8de26c3","https://git.kernel.org/stable/c/8a0f0f9ef41cb80de4d5da4ae146df3075463f6b","https://git.kernel.org/stable/c/6c9c9367351a461d62e5c0a39bffdcfbb40f068b","https://git.kernel.org/stable/c/3bc82999fb85cecc7eb6ec1755ee7d698aa1e783","https://git.kernel.org/stable/c/94af6cd832e9b4ce39a8fb59144a8f09ab56fd35","https://git.kernel.org/stable/c/c8ccd3b2013daaf77b98f8a6724fcf4d2c5c52d6","https://git.kernel.org/stable/c/845a2737e0f5ffe5ca8d38de556012b0c9472cdd"],"sources":[{"name":"CVE","id":"CVE-2026-98751","modified":"2026-10-30T12:39:21.567Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98751"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T14:04:52.455Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T23:35:33.875Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
