CVE-2026-31650

The CVE concerns the Linux kernel mmc vub300 driver. The root cause is a use-after-free risk from device-managed controller allocation and a lifetime tie to the parent USB device rather than the interface, which can cause memory leaks if the driver is unbound without a disconnect. A last referenc...
