Linux Kernel qla2xxx Driver PCI Error Handling Vulnerability

A vulnerability in the Linux kernel's qla2xxx SCSI driver has been addressed. The issue arose from the driver prematurely accessing hardware after a recoverable PCI error. Following such an error, the driver should verify whether the error condition persists and wait for the operating system to signal a resume. This flaw could lead to missed error conditions and improper handling of PCI communications, potentially causing timeouts and failures in firmware operations.

Impact

The vulnerability could disrupt proper PCI error recovery, leading to timeouts and failures in handling firmware dumps for the affected QLogic devices.
