CVE-2022-25657Network attack vector

Memory corruption via invalid MKV seek header

Published Sep 2, 2022 · Updated Aug 3, 2024

Buffer overflow in Qualcomm Snapdragon video parsing allows remote attackers to trigger memory corruption through an invalid MKV clip. The parser mishandles an invalid seek header while processing the clip, corrupting memory in affected multimedia firmware. The malformed file must reach a vulnerable Snapdragon video parser; the record does not establish code execution, so impact is bounded to the documented memory-corruption effects.
