CVE-2022-22074

Memory corruption via overflowing WMA buffer size

Published Sep 16, 2022 · Updated Aug 3, 2024

Integer-overflow memory corruption in Qualcomm Snapdragon audio allows local users to corrupt memory during WMA file playback. The audio component derives a WMA buffer size with an overflowing integer calculation, producing an undersized buffer for the subsequent data operation. Reachability requires WMA playback on an affected chipset; Qualcomm reports no required privileges or user interaction and confines the flaw to the audio path.
