In the Linux kernel, the following vulnerability has been resolved:

scsi: qla2xxx: Hold vport reference in qla24xx_report_id_acquisition()

In the format 1 path, the virtual port is located on ha->vp_list while holding vport_slock, but the lock is dropped before vp is used: qla_update_host_map() is called and VP_IDX_ACQUIRED/REGISTER_FC4_NEEDED/ REGISTER_FDMI_NEEDED are set on vp. No reference is taken across that window, so a concurrent qla24xx_deallocate_vp_id() can tear the vport down and free it, leading to a use-after-free.

Take a vport reference (vref_count) under vport_slock when the matching vp is found, and drop it after the last use of vp. qla24xx_deallocate_vp_id() waits for vref_count to reach zero before unlinking and freeing the vport, so the pointer stays valid. This matches the reference idiom already used by the other ha->vp_list traversals.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
