By removing the queue_index check, it is\npossible for multiple napi instances to access the Rx ring at the same time,\nwhich will result in a corrupted ring state which can lead to a crash when\nflushing the rings in __xsk_flush(). This can happen when the linked list of\nsockets to flush gets corrupted by concurrent accesses. A quick and small fix\nis not possible, so let us revert this for now."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/xdp/xsk.c"],"versions":[{"version":"2863d665ea41282379f108e4da6c8a2366ba66db","lessThan":"19cb40b1064566ea09538289bfcf5bc7ecb9b6f5","status":"affected","versionType":"git"},{"version":"2863d665ea41282379f108e4da6c8a2366ba66db","lessThan":"7fcf26b315bbb728036da0862de6b335da83dff2","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/xdp/xsk.c"],"versions":[{"version":"6.9","status":"affected"},{"version":"0","lessThan":"6.9","status":"unaffected","versionType":"semver"},{"version":"6.9.5","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":"6.9","versionEndExcluding":"6.9.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.9","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/19cb40b1064566ea09538289bfcf5bc7ecb9b6f5"},{"url":"https://git.kernel.org/stable/c/7fcf26b315bbb728036da0862de6b335da83dff2"}],"title":"Revert \"xsk: Support redirect to any socket bound to the same umem\"","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-06-25T20:47:03.644056Z","id":"CVE-2024-39293","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-25T20:47:15.195Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T04:19:20.676Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/19cb40b1064566ea09538289bfcf5bc7ecb9b6f5","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/7fcf26b315bbb728036da0862de6b335da83dff2","tags":["x_transferred"]}]}]}}
