MediaTek Dimensity 7300 vulnerability threatens smartphone security
Researchers at Ledger have uncovered a critical vulnerability in the popular MediaTek Dimensity 7300 chip, which can be exploited through an electromagnetic attack to gain full control over the device. Due to a flaw in the boot ROM, this issue cannot currently be patched. This vulnerability compromises the security of devices such as Solana Seeker smartphones that use this processor, making them unsafe for storing private cryptographic keys.
