AnalysisAIv1 – Sep 15, 2026

An out-of-bounds write in the Goodix fingerprint trusted-application test handler (gf_ta_test_set_config in gf_ta_test.c) on Android allows a locally installed application holding low privileges to corrupt memory and escalate to kernel-level privileges without any user interaction. The flaw stems from improper validation of caller-supplied input reaching a memory-write path inside the fingerprint TA interface. Google addressed it in the Pixel security bulletin dated 2026-09-01; no public exploit code or CISA KEV entry was identified at time of analysis.

Attack Technique

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
