CVE-2022-50827

Kernel memory leak via incomplete allocation unwind

Published Dec 30, 2025 · Updated Dec 30, 2025

Memory leak in the lpfc SCSI driver in Linux 5.14, 5.15 before 5.15.76, and 6.0 before 6.0.6 allows attackers to cause unspecified impact. On a VMID allocation failure, lpfc_create_port branches to an exit path that returns without releasing VMID resources or the SCSI host reference. Reachability requires an allocation failure during lpfc port creation; upstream material does not establish that an unprivileged user can force that failure.
