CVE-2026-58856

Local information disclosure via unchecked camera buffer read

Published Oct 5, 2026 · Updated Oct 5, 2026

Out-of-bounds read in Google Android 14, 15, 16, 16-qpr2, and 17 allows local users to disclose information through camera buffers. The returnOutputBufferLocked function in DeprecatedCamera3StreamSplitter.cpp handles an output buffer without a required bounds check, permitting a read beyond its boundary. Exploitation needs local execution but no additional execution privileges or user interaction; Google does not specify the disclosed data or precise trigger.
