CVE-2024-23378

Memory corruption via unchecked audio IOCTL input

Published Oct 7, 2024 · Updated Oct 7, 2024

Memory corruption in Qualcomm Snapdragon Auto audio firmware allows local users to corrupt memory through MSM module IOCTL calls. The MSM audio path copies user-space input during playback or recording without checking its size before the buffer operation. Access requires high local privileges and no user interaction; Qualcomm has not disclosed the exact IOCTL, destination buffer, or resulting execution path.
