CVE-2026-56985: Google Pixel KeyMint type confusion privilege escalation

CVE-2026-56985 · Severity: high · CVSS 8.4 · Published 2026-09-15

KeyMint is Google Pixel's cryptographic key management system that secures sensitive operations like digital signatures. A type confusion flaw in multiple files allows attackers to bypass signature protections and gain elevated device privileges without needing to exploit other vulnerabilities or trick users. This could allow an attacker with basic device access to compromise the entire security of Pixel devices.

Technologies: Google Android, Google Pixel Firmware. Vendors: Google.
