CVE-2022-50554

CVE-2022-50554 affects the Linux kernel's blk-mq subsystem. The vulnerability arises from a race around IO request queuing, where an in-flight ->queue_rq() may be double-called due to an timeout occurring after blk_mq_start_request() but before completion, potentially causing a kernel panic. T...
