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...

CVE-2026-31604

The CVE-2026-31604 issue concerns the Linux kernel’s wifi: rtw88 driver. A memory leak arose because the driver grabbing a reference to the USB device during probe did not release it on all probe errors (e.g., descriptor parsing failures) while the interface remained bound to a driver. The fix dr...

CVE-2026-31582

CVE-2026-31582 affects the Linux kernel hwmon powerz driver. A use-after-free occurs when a USB disconnect frees the URB and mutex, and a subsequent powerz_read() can dereference the freed URB in powerz_read_data(). The fix, as described across sources, is to set priv->urb to NULL in powerz_di...

CVE-2026-31578

CVE-2026-31578: Linux kernel as102_usb driver race leads to use-after-free/double-free when a device is deregistered while an open FD remains. The crash arises from freeing as102_dev_t after usb_register_dev() and before the final FD is closed; the fix defers freeing to the .release() path, ensur...
