CVE-2025-71070

A reference count leak flaw was found in the Linux kernel's ublk userspace block driver subsystem. When a ublk server process exits while requests are still pending, the reference counts for those requests are not properly decremented. This leads to WARNONONCE warnings and could potentially allow...
