Transient service interruption via image-encoding IOCTL over-read
Published Oct 9, 2025 · Updated Oct 9, 2025
A buffer over-read in Qualcomm Snapdragon image encoding allows local users with low privileges to temporarily interrupt service. The camera component reads beyond the intended buffer while processing an image-encoding IOCTL; Qualcomm has not disclosed the specific function or omitted bounds check. Reachability requires local low-privileged access to the IOCTL, and the documented consequence is a transient availability interruption without reported data disclosure or modification.
