Ledger’s latest security report reveals that the MediaTek Dimensity 7300 smartphone chip, used in the Solana Seeker and various other devices, contains a critical hardware vulnerability. This flaw could allow attackers to gain full control of a device and extract users’ crypto private keys once they have physical access. As the issue originates from the chip itself, the vulnerability cannot be fixed through software patches, making it a widespread and persistent security risk.
Ledger researchers stated that, during testing, they successfully attacked the chip’s boot process using “electromagnetic fault injection,” bypassing security mechanisms and gaining complete system access. Once compromised, all sensitive data on the device is left unprotected. This vulnerability is particularly concerning for the Solana Seeker phone, which touts crypto-centric features as its main selling point.
The research team noted that, although the success rate for a single attack is only 0.1% to 1%, the process can be rapidly repeated, meaning an attacker could potentially compromise a device within minutes after several attempts. Ledger discovered the issue in February and reported it to MediaTek in May. MediaTek responded that the Dimensity 7300 is a consumer-grade chip, not originally designed for financial or hardware security module-level environments, and that device manufacturers should implement additional measures to defend against physical attacks.
Meanwhile, Solana Mobile is building an ecosystem around the Seeker device and plans to launch a native governance token, SKR, in early 2026. The token will have a total supply of 10 billion, with 30% allocated for airdrops, 25% for ecosystem growth, and the remainder distributed among liquidity, community treasury, Solana Mobile, and Solana Labs. According to the official statement, SKR will give holders real governance rights over the mobile platform and will use a linear inflation mechanism to incentivize early stakers. More information is expected to be announced at the Solana Breakpoint conference in December.
With this hardware vulnerability coming to light, the security of crypto user devices is once again in the industry spotlight. Institutions and developers need to reassess the security boundaries of mobile devices as entry points for crypto, ensuring user asset safety even when underlying chips have inherent flaws.
