Ledger has identified a critical security vulnerability in a widely used smartphone chip that is reportedly unpatchable. The discovery highlights a hardware-level flaw that cannot be rectified through standard software updates, leaving affected devices permanently exposed to specific attack vectors. This finding raises significant concerns for mobile security, particularly regarding the safety of private keys and sensitive data stored on smartphones. Since the vulnerability exists at the chip level, users of affected devices may need to rely on alternative security measures or hardware wallets to ensure the safety of their assets.
