CVE-2024-43063

Local information disclosure via mailbox buffer over-read

Published Jan 6, 2025 · Updated Jan 6, 2025

Buffer over-read in Qualcomm Snapdragon Auto allows local users with low privileges to disclose information through the mailbox read API. The mailbox read API reads beyond a buffer boundary during a read request, but Qualcomm has not published the affected function or omitted bounds check. Low-privileged local access is required, and the published impact is limited to information disclosure and limited service degradation.
