CVE-2022-48758: scsi: bnx2fc: Flush destroy_work queue before calling bnx2fc_interface_put()

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.21% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 00849de10f798a9538242824a51b1756e7110754, 262550f29c750f7876b6ed1244281e72b64ebffb, 2a12fe8248a38437b95b942bbe85aced72e6e2eb.

Low priority for now. Upgrade to Linux Linux 00849de10f798a9538242824a51b1756e7110754, 262550f29c750f7876b6ed1244281e72b64ebffb, 2a12fe8248a38437b95b942bbe85aced72e6e2eb or later.

In the Linux kernel, the following vulnerability has been resolved: scsi: bnx2fc: Flush destroy_work queue before calling bnx2fc_interface_put() The bnx2fc_destroy() functions are removing the interface before calling destroy_work. This results multiple WARNings from sysfs_remove_group() as the controller rport device attributes are removed too early. Replace the fcoe_port's destroy_work queue. It's not needed. The problem is easily reproducible with the following steps. Example: $ dmesg -w & $ systemctl enable --now fcoe $ fipvlan -s -c ens2f1 $ fcoeadm -d ens2f1.802 [ 583.464488] host2: libfc: Link down on port (7500a1) [ 583.472651] bnx2fc: 7500a1 - rport not created Yet!!

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
