[ Upstream commit 9c6ba456711687b794dcf285856fc14e2c76074f ] The powermate driver expects at least one valid USB endpoint in its probe function. If given malicious descriptors that specify 0 for the number of endpoints, it will crash. Validate the number of endpoints on the interface before using them.
