Ledger warns Mediatek Dimensity 7300 has unpatchable hardware security flaws
A report from hardware security researchers at Ledger flags the Mediatek Dimensity 7300 as potentially susceptible to low-level compromise that cannot be fully mitigated with software updates. Ledger’s findings indicate vulnerabilities at the silicon level that, depending on implementation, could allow attackers to bypass OS protections and access sensitive operations that underpin mobile wallet security.
Why this matters: phones and devices built on the affected SoC may not be able to guarantee the integrity of private keys or secure elements, increasing risk for on-device key storage and mobile signing. Ledger urges Mediatek, OEMs, and the wider crypto community to investigate and disclose device scope; meanwhile users and custodians should consider hardware wallets or isolating critical keys off affected devices until vendors provide clarity or hardware revisions.
