Memory corruption via unchecked QCP chunk size
Published Mar 4, 2024 · Updated Aug 2, 2024
Memory corruption in Qualcomm Snapdragon firmware allows remote attackers to alter memory via a QCP clip with an invalid chunk size. The QCP media parser copies chunk data without validating the declared chunk size against the destination buffer. No privileges or user interaction are required; successful corruption can affect confidentiality, integrity, and availability.
