{"id":"CVE-2024-46842","summary":"scsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_info","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_info\n\nThe MBX_TIMEOUT return code is not handled in lpfc_get_sfp_info and the\nroutine unconditionally frees submitted mailbox commands regardless of\nreturn status.  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.","modified":"2026-03-20T12:37:57.496801Z","published":"2024-09-27T12:39:36.370Z","related":["SUSE-SU-2024:3984-1","SUSE-SU-2024:3986-1","SUSE-SU-2024:4315-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4364-1","SUSE-SU-2024:4376-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/46xxx/CVE-2024-46842.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/bba47fe3b038cca3d3ebd799665ce69d6d273b58"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ede596b1434b57c0b3fd5c02b326efe5c54f6e48"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/46xxx/CVE-2024-46842.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-46842"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"479b0917e4477f49df2e3be454aac3cfa5dec171"},{"fixed":"bba47fe3b038cca3d3ebd799665ce69d6d273b58"},{"fixed":"ede596b1434b57c0b3fd5c02b326efe5c54f6e48"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-46842.json"}}],"schema_version":"1.7.5"}
