CVE-2022-22087Network attack vector

Memory corruption via unchecked MKV buffer copy

Published Jun 14, 2022 · Updated Aug 3, 2024

A buffer overflow in Qualcomm Snapdragon video firmware allows remote attackers to corrupt memory by supplying a crafted MKV clip. The proprietary MKV parser copies clip data into a buffer without checking the input size before the copy. No authentication or user interaction is required, and successful exploitation corrupts memory in the video component.
