cve 2025 68745

CVE-2025-68745 is a Linux kernel vulnerability in the qla2xxx driver, which manages QLogic Fibre Channel host bus adapters. The flaw involved a regression that caused SCSI target commands to become stuck after a chip reset and introduced dangerous race conditions around DMA unmapping. Kernel maintainers responded by reverting the offending changes and applying a surgical correction to the abort path. This tag covers discussions about the vulnerability, its impact on storage systems, and the kernel patches that fixed it. Topics include DMA race conditions, SCSI command handling, and driver stability in enterprise Linux environments.
