CVE-2026-97528

/// Technical 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.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
