CVE-2019-10581Network attack vector

Remote memory corruption via stale global audio pointer

Published Jan 21, 2020 · Updated Aug 4, 2024

Use-after-free in Qualcomm Snapdragon audio components allows remote attackers to access freed memory through a network-reachable audio path. The cleanup path frees an audio-device object but assigns NULL to a local pointer instead of the global static pointer, leaving the global pointer dangling. Network access and no authentication are required; Qualcomm does not identify the triggering audio operation or resulting execution context.
