In multiple functions of rw_t3t.cc, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Remote code execution is possible in Android's NFC Type 3 Tag processing layer (rw_t3t.cc within libnfc-nci) across Android 14 through 17 via an integer overflow that triggers a heap out-of-bounds write. No user interaction or additional privileges are required per the description, making this exploitable by any attacker within NFC proximity of an unpatched device. …
