CVE-2026-58790 · Severity: info · Published 2026-11-10

Google Pixel devices include hardware codec firmware that encodes video and audio. A buffer overflow in the encoder's CMD_ENC_SET_PARAM command allows a local attacker with execution privileges to overflow a non-heap buffer and escalate their access on the device. This could lead to complete device compromise.

## How to fix

- Fixed in 2026-11-05 security patch level

## Technical details

A non-heap buffer overflow exists in the CMD_ENC_SET_PARAM handler of the HWCodec firmware encoder component. The vulnerability requires local access and execution privileges, with user interaction needed for exploitation. A successful exploit grants elevated privileges within the firmware execution context.
