The issue is that for MBX_TIMEOUT cases, when firmware\nreturns SFP information at a later time, that same mailbox memory region\nreferences previously freed memory in its cmpl routine.\n\nFix by adding checks for the MBX_TIMEOUT return code.  During mailbox\nresource cleanup, check the mbox flag to make sure that the wait did not\ntimeout.  If the MBOX_WAKE flag is not set, then do not free the resources\nbecause it will be freed when firmware completes the mailbox at a later\ntime in its cmpl routine.\n\nAlso, increase the timeout from 30 to 60 seconds to accommodate boot\nscripts requiring longer timeouts."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/lpfc/lpfc_els.c"],"versions":[{"version":"479b0917e4477f49df2e3be454aac3cfa5dec171","lessThan":"bba47fe3b038cca3d3ebd799665ce69d6d273b58","status":"affected","versionType":"git"},{"version":"479b0917e4477f49df2e3be454aac3cfa5dec171","lessThan":"ede596b1434b57c0b3fd5c02b326efe5c54f6e48","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/scsi/lpfc/lpfc_els.c"],"versions":[{"version":"6.2","status":"affected"},{"version":"0","lessThan":"6.2","status":"unaffected","versionType":"semver"},{"version":"6.10.10","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11","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":"6.2","versionEndExcluding":"6.10.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bba47fe3b038cca3d3ebd799665ce69d6d273b58"},{"url":"https://git.kernel.org/stable/c/ede596b1434b57c0b3fd5c02b326efe5c54f6e48"}],"title":"scsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_info","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-29T13:59:24.823160Z","id":"CVE-2024-46842","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":"2024-09-29T13:59:29.321Z"}}]}}
