AI-suggested

A fix is available and has been applied in Linux kernel version 6.6 and related commits. Users should update to Linux kernel 6.6 or later where the per-fcport spinlock serialization is implemented to prevent concurrent list corruption. No additional mitigation is required beyond applying the official fix.

Description

CVE-2026-97527 is a high-severity vulnerability in the Linux kernel's qla2xxx SCSI driver. It involves improper serialization of the NVMe unsolicited context list (unsol_ctx_head) accessed concurrently without a dedicated lock. This can lead to list corruption due to concurrent modifications from multiple contexts. The issue is fixed by introducing a per-fcport spinlock to serialize list operations, preventing race conditions and ensuring data integrity.
