Remote privilege escalation via uninitialized out-of-bounds writes
Published Oct 5, 2026 · Updated Oct 5, 2026
Out-of-bounds writes in Google Android 16, 16-qpr2, and 17 allow remote attackers to escalate privileges without user interaction. The affected code uses uninitialized data in multiple undisclosed locations, resulting in writes beyond buffer bounds; the CNA names no function or input path. Exploitation requires access to an undisclosed remote attack surface, and the published record does not establish a more specific consequence.
