CVE-2026-0056

Local information disclosure via unchecked style count

Published Jun 1, 2026 · Updated Jun 1, 2026

Out-of-bounds read in Android 14, 15, 16, and 16-qpr2 allows local users to disclose process memory through a malformed APK. ResourceTypes.cpp setTo trusts ResStringPool_header.styleCount without validating it against the string-pool chunk, so parsing an invalid count reads beyond the chunk. A local low-privileged process can trigger the parser without user interaction or additional execution privileges; integrity and availability are unaffected.
