Commit\nfb6791d100d1b started exploiting this behavior to speed up filesystem\nunmount: gfs2 would simply free glocks it didn't want to unlock and then\nrelease the lockspace.  This didn't take the bast callbacks for\nasynchronous lock contention notifications into account, which remain\nactive until until a lock is unlocked or its lockspace is released.\n\nTo prevent those callbacks from accessing deallocated objects, put the\nglocks that should not be unlocked on the sd_dead_glocks list, release\nthe lockspace, and only then free those glocks.\n\nAs an additional measure, ignore unexpected ast and bast callbacks if\nthe receiving glock is dead."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/gfs2/glock.c","fs/gfs2/glock.h","fs/gfs2/incore.h","fs/gfs2/lock_dlm.c","fs/gfs2/ops_fstype.c","fs/gfs2/super.c"],"versions":[{"version":"fb6791d100d1bba20b5cdbc4912e1f7086ec60f8","lessThan":"0636b34b44589b142700ac137b5f69802cfe2e37","status":"affected","versionType":"git"},{"version":"fb6791d100d1bba20b5cdbc4912e1f7086ec60f8","lessThan":"e42e8a24d7f02d28763d16ca7ec5fc6d1f142af0","status":"affected","versionType":"git"},{"version":"fb6791d100d1bba20b5cdbc4912e1f7086ec60f8","lessThan":"501cd8fabf621d10bd4893e37f6ce6c20523c8ca","status":"affected","versionType":"git"},{"version":"fb6791d100d1bba20b5cdbc4912e1f7086ec60f8","lessThan":"d98779e687726d8f8860f1c54b5687eec5f63a73","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/gfs2/glock.c","fs/gfs2/glock.h","fs/gfs2/incore.h","fs/gfs2/lock_dlm.c","fs/gfs2/ops_fstype.c","fs/gfs2/super.c"],"versions":[{"version":"3.8","status":"affected"},{"version":"0","lessThan":"3.8","status":"unaffected","versionType":"semver"},{"version":"6.6.33","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.8.12","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9.3","lessThanOrEqual":"6.9.*","status":"unaffected","versionType":"semver"},{"version":"6.10","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8","versionEndExcluding":"6.6.33"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8","versionEndExcluding":"6.8.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8","versionEndExcluding":"6.9.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0636b34b44589b142700ac137b5f69802cfe2e37"},{"url":"https://git.kernel.org/stable/c/e42e8a24d7f02d28763d16ca7ec5fc6d1f142af0"},{"url":"https://git.kernel.org/stable/c/501cd8fabf621d10bd4893e37f6ce6c20523c8ca"},{"url":"https://git.kernel.org/stable/c/d98779e687726d8f8860f1c54b5687eec5f63a73"}],"title":"gfs2: Fix potential glock use-after-free on unmount","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T04:12:25.837Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/0636b34b44589b142700ac137b5f69802cfe2e37","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/e42e8a24d7f02d28763d16ca7ec5fc6d1f142af0","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/501cd8fabf621d10bd4893e37f6ce6c20523c8ca","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/d98779e687726d8f8860f1c54b5687eec5f63a73","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-38570","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T17:14:22.126008Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-11T17:34:56.284Z"}}]}}
