Alert meAnalysisAIv1 – Sep 16, 2026
An out-of-bounds write in Av1DecodeFrameTag (vp9hwd_headers.cc) in the Android media decoding stack allows crafted AV1/VP9 media content to corrupt memory and potentially achieve remote code execution in the codec process, which runs with elevated system privileges relative to a normal app. Google's Pixel security bulletin dated 2026-09-01 lists the fix, and no user interaction is required, though the provided CVSS vector (PR:L) implies the attacker must already be able to route content into the decoder path. No EPSS score, CISA KEV entry, or public exploit code was supplied with this record, so active exploitation is unconfirmed.

Priority Score
Attack Technique
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
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.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
