AI-suggested
A fix has been implemented in the Linux kernel to skip vports marked for deletion during report ID acquisition, preventing re-registration and use-after-free. Users should update to patched versions of the linux-azure kernel. Patch status is not explicitly stated here, so check the vendor advisory for current remediation guidance.
Description
A vulnerability in the Linux kernel's scsi qla2xxx driver was resolved that involved improper handling of virtual port (vport) deletion during report ID acquisition. The flaw allowed a vport marked for deletion to be re-registered in the host map, leading to potential use-after-free memory dereference. This could result in high impact on confidentiality, integrity, and availability. The issue affects specific linux-azure kernel versions.
