Local information disclosure via unchecked EAVB packet copy
Published Aug 6, 2025 · Updated Aug 6, 2025
Buffer overflow in Qualcomm Snapdragon Auto EAVB BE packet processing allows local users to read information through an invalid header length. The EAVB BE packet path performs an unchecked buffer copy while processing the attacker-controlled length, producing the disclosure. Exploitation requires low-privilege local access and affects confidentiality without altering data or interrupting service.
