CVE-2026-46109

A flaw was found in the Linux kernel's USB ULPI Ultra Low Pin Interface subsystem. This memory leak vulnerability occurs during error handling in the ulpiregister function. If certain registration failures occur, allocated memory is not properly released, which could lead to resource exhaustion a...

CVE-2026-31759

CVE-2026-31759 affects the Linux kernel USB ULPI path (usb: ulpi) where a double free could occur in ulpi_register_interface() after a failed device_register(), because the error path freed ulpi twice. The root cause is a missing delegation of cleanup to put_device() via ulpi_dev_release(), preve...
