Ledger has raised alarms about a flaw found in a MediaTek processor used in several Android devices, including the Solana
In its report released on December 3, Ledger said it tested the MediaTek Dimensity 7300 (MT6878) and bypassed its protections.
The company described the result as gaining “full and absolute control over the smartphone, with no security barrier left standing”.

Security researchers Charles Christen and Léo Benito from Ledger explained that they performed the attack using electromagnetic pulses during the chip’s early startup phase. This lets them interfere with the processor before its normal security systems can activate.
According to the researchers, this flaw means the devices cannot safely store or use private keys. The problem is built into the hardware itself, so it cannot be fixed through software updates.
Because the weakness is part of the chip’s design, users remain exposed even after the issue becomes known.
The engineers said that while each attempt to exploit the flaw has a low success rate, between 0.1% and 1%, attackers could try repeatedly. Since the process can be attempted about once per second, they estimate that access could be gained in just a few minutes.
MediaTek responded that these kinds of electromagnetic fault attacks are “out of scope” for the MT6878 chip. The company said the processor was designed for general consumer devices, not for sensitive applications such as finance or secure hardware modules.
