Description
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to improper input validation in the pegasus USB driver when handling USB endpoints during device probing. A remote attacker can connect a malicious USB device with invalid or unexpected endpoint configurations to cause a denial of service.
Exploitation does not require authentication or user interaction beyond physically connecting the device; however, the attack vector is considered local due to physical access requirement.
Remediation
Install security update from vendor's repository.
