Ledger researchers have uncovered a critical vulnerability in MediaTek’s Dimensity 7300 chip that could allow attackers with physical access to an Android device to extract wallet PINs and seed phrases in less than a minute. The flaw resides in the chip’s boot ROM — code permanently embedded during manufacturing — meaning it cannot be patched through software updates. By using precisely timed voltage glitches during startup, attackers can bypass security checks and gain the highest systеm privileges, allowing them to decrypt protected data such as private keys.
The vulnerability may affect millions of mid-range Android devices, including the Solana Seeker phone. While a software mitigation is expected in the March 2026 Android Security Bulletin, the underlying hardware issue remains unresolved.
