In my case, the tag was hold by a keep alive request\nwaiting inside admin_q, as we quiesced admin_q while reset ctrl, so the\nrequest maked as idle and will not process before reset success. As\nfabric_q shares tagset with admin_q, while reconnect remote target, we\nneed a tag for connect command, but the only one reserved tag was held\nby keep alive command which waiting inside admin_q. As a result, we\nfailed to reconnect admin_q forever. In order to fix this issue, I\nthink we should keep two reserved tags for admin queue."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/nvme/host/core.c","drivers/nvme/host/fabrics.h"],"versions":[{"version":"ed01fee283a067c72b2d6500046080dbc1bb9dae","lessThan":"149afee5c7418ec5db9d7387b9c9a5c1eb7ea2a8","status":"affected","versionType":"git"},{"version":"ed01fee283a067c72b2d6500046080dbc1bb9dae","lessThan":"ff2f90f88d78559802466ad1c84ac5bda4416b3a","status":"affected","versionType":"git"},{"version":"ed01fee283a067c72b2d6500046080dbc1bb9dae","lessThan":"6851778504cdb49431809b4ba061903d5f592c96","status":"affected","versionType":"git"},{"version":"ed01fee283a067c72b2d6500046080dbc1bb9dae","lessThan":"262da920896e2f2ab0e3947d9dbee0aa09045818","status":"affected","versionType":"git"},{"version":"ed01fee283a067c72b2d6500046080dbc1bb9dae","lessThan":"de105068fead55ed5c07ade75e9c8e7f86a00d1d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/nvme/host/core.c","drivers/nvme/host/fabrics.h"],"versions":[{"version":"5.12","status":"affected"},{"version":"0","lessThan":"5.12","status":"unaffected","versionType":"semver"},{"version":"6.1.83","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.23","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.7.11","lessThanOrEqual":"6.7.*","status":"unaffected","versionType":"semver"},{"version":"6.8.2","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9","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":"5.12","versionEndExcluding":"6.1.83"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.12","versionEndExcluding":"6.6.23"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.12","versionEndExcluding":"6.7.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.12","versionEndExcluding":"6.8.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.12","versionEndExcluding":"6.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/149afee5c7418ec5db9d7387b9c9a5c1eb7ea2a8"},{"url":"https://git.kernel.org/stable/c/ff2f90f88d78559802466ad1c84ac5bda4416b3a"},{"url":"https://git.kernel.org/stable/c/6851778504cdb49431809b4ba061903d5f592c96"},{"url":"https://git.kernel.org/stable/c/262da920896e2f2ab0e3947d9dbee0aa09045818"},{"url":"https://git.kernel.org/stable/c/de105068fead55ed5c07ade75e9c8e7f86a00d1d"}],"title":"nvme: fix reconnection fail due to reserved tag allocation","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-noinfo Not enough information"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.5,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2024-05-31T18:39:12.435774Z","id":"CVE-2024-27435","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":"2024-11-06T16:36:56.843Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T00:34:52.327Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/149afee5c7418ec5db9d7387b9c9a5c1eb7ea2a8","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/ff2f90f88d78559802466ad1c84ac5bda4416b3a","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/6851778504cdb49431809b4ba061903d5f592c96","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/262da920896e2f2ab0e3947d9dbee0aa09045818","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/de105068fead55ed5c07ade75e9c8e7f86a00d1d","tags":["x_transferred"]}]}]}}
