On the\nerror (out:) path the function frees uctx with kfree() but never removes\nit from the list. This leaves a freed node in fcport->unsol_ctx_head: the\nnext list_add_tail() for that fcport writes through the freed node, and a\nsubsequent list_del() can corrupt the list or panic.\n\nUnlink uctx with list_del() before kfree() on the error path, matching the\nother free sites in qla_nvme_release_lsrsp_cmd_kref() and\nqla2xxx_process_purls_pkt(). qla2x00_rel_sp() in the failure path only\nreturns the SRB to its pool and does not invoke sp->put_fn, so the out:\npath is the sole free and uctx is always still linked there.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · updated 2026-09-28 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-97528.json)","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":211010,"id":"CVE-2026-97528","ts":1790349124082,"field":"cvss","old":null,"new":"8.8"},{"seq":211009,"id":"CVE-2026-97528","ts":1790349124082,"field":"severity","old":"none","new":"high"}]}
