CVE-2022-48846 is a memory leak vulnerability in the Linux kernel's block subsystem, specifically affecting versions prior to 5.18. The flaw occurs because request queue quality of service (rq qos) structures are not properly released for queues without an associated disk, such as un-present SCSI LUNs or NVMe admin queues. This medium-severity vulnerability (CVSS 5.5) has a local attack vector with low complexity, requiring local privileges and resulting in high availability impact due to the memory leak. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
