CVE-2025-27045

Local information disclosure via batch command over-read

Published Oct 9, 2025 · Updated Oct 9, 2025

Buffer over-read in the Qualcomm Snapdragon Video driver allows local users with low privileges to disclose information during batch commands. The Video driver reads beyond the intended buffer boundary while processing batch command execution, but Qualcomm has not published a more specific code locus. A low-privileged local process can reach the flaw without user interaction; the over-read discloses memory and causes a limited service interruption.
