CVE-2026-58808 · Severity: info · Published 2026-11-10

A flaw in Google Pixel device firmware allows secure cache memory to be dumped into non-secure memory during a warm reset, exposing sensitive data. An attacker with system-level access can exploit this missing permission check to read protected information without user interaction. This could compromise encryption keys, credentials, or other confidential data stored in secure cache.
