CVE-2024-36952: scsi: lpfc: Move NPIV's transport unregistration to after resource clean up

Noroxi assessment

Priority: Monitor (action score 18/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Linux Linux 0936809d968ecf81e0726fbd02ff2a5732d960c3, 4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c, 718602cd15f4c5710850090ea3066a89eeb46278.

Low priority for now. Upgrade to Linux Linux 0936809d968ecf81e0726fbd02ff2a5732d960c3, 4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c, 718602cd15f4c5710850090ea3066a89eeb46278 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Move NPIV's transport unregistration to after resource clean up There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric. Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch. Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID and LOGO are sent.
