AI risk analysis

Summary: This flaw in the Linux kernel's qla2xxx driver for the QLogic Fibre Channel HBA allows an attacker to corrupt the unsolicited context list, potentially leading to a denial of service or kernel panic.
Exploitability: Exploitation requires the attacker to trigger an LS reject error on an NVMe device, which is relatively difficult and requires specific conditions to be met.
Blast radius: If exploited, the vulnerability could lead to a denial of service or kernel panic, impacting the stability and availability of the affected system.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to the fixed version 10.3.22 or later.

NVD description

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Unlink NVMe unsol ctx before freeing on LS reject error qla_nvme_xmt_ls_rsp() obtains uctx, which was linked into fcport->unsol_ctx_head by qla2xxx_process_purls_iocb() and is still linked when the NVMe transport calls back to transmit the LS response. On the error (out:) path the function frees uctx with kfree() but never removes it from the list. This leaves a freed node in fcport->unsol_ctx_head: the next list_add_tail() for that fcport writes through the freed node, and a subsequent list_del() can corrupt the list or panic. Unlink uctx with list_del() before kfree() on the error path, matching the other free sites in qla_nvme_release_lsrsp_cmd_kref() and qla2xxx_process_purls_pkt(). qla2x00_rel_sp() in the failure path only returns the SRB to its pool and does not invoke sp->put_fn, so the out: path is the sole free and uctx is always still linked there.
