Security Flaw Discovered in Solana Seeker’s Core Chip, According to Ledger Report

A serious security vulnerability has been identified in a smartphone chip utilized by the Solana Seeker and various other devices. This flaw poses significant risks to cryptocurrency holders, potentially allowing unauthorized access to devices and theft of private keys, as detailed in a recent report by Ledger.

Key Takeaways:

Ledger has discovered an unrectifiable flaw in the MediaTek Dimensity 7300 chip, posing threats of complete device takeovers and private key theft.
The vulnerability targets the phone's booting process, enabling hackers with physical access to bypass security measures in a matter of minutes.
There is no software solution available to remedy the flaw, as the vulnerability is inherent to the chip's hardware.

In a study released on Wednesday, researchers from Ledger, a well-known hardware wallet manufacturer, announced that they successfully exploited the MediaTek Dimensity 7300 chip. They were able to bypass its security measures, achieving what they termed “full and absolute control” over an affected device.

The researchers cautioned that this vulnerability allows attackers, who have physical access to the device, to extract sensitive information, including cryptographic keys essential for securing digital assets.

Boot-Phase Attack Exposes Solana Seeker Chip

The chip powers numerous smartphones, particularly the Solana Seeker, which is marketed as a mobile gateway for decentralized applications.

Ledger’s security experts, Charles Christen and Léo Benito, indicated that the exploit is based on electromagnetic fault injection occurring during the chip’s initial boot phase.

By carefully interfering with this process, the team managed to bypass memory protections and overwrite built-in security protocols within the system-on-chip.

“The result is total compromise,” the researchers stated, noting that once the attack is executed successfully, there are no remaining technical barriers preventing access to the data stored on the device.

Crucially for cryptocurrency users, this flaw cannot be rectified through software updates or patches.

Since the weakness is embedded in the silicon, it is permanent for all devices operating on the affected chipset. The researchers wrote, “Users remain exposed even after disclosure.”

Although the likelihood of success in an individual attempt is relatively low—estimated between 0.1% and 1%—the attack can be repeated in quick succession. Ledger estimates that with enough attempts, a compromise could occur in just a few minutes.

MediaTek informed Ledger that this issue falls outside the design parameters of the Dimensity 7300.

In their statement, the company clarified that the chip was designed for everyday consumer smartphones, not for environments requiring secure enclaves like those utilized in financial infrastructure or hardware security modules.

“For products managing sensitive cryptographic data, manufacturers should implement specialized protections against physical attacks,” MediaTek advised.

Ledger disclosed this vulnerability to MediaTek in early May, following the commencement of tests in February. The chipmaker has since alerted device vendors that may be affected.

Solana Mobile Announces SKR Governance Token Launch in 2026

In 2026, Solana Mobile intends to launch SKR, a native token linked to its Seeker phone, establishing it as the governance token for its mobile ecosystem.

The total supply of the token will be capped at 10 billion, with 30% allocated for airdrops and 25% designated for growth and partnerships.

Additional allocations include 10% for liquidity, 10% for a community treasury, 15% for Solana Mobile, and 10% for Solana Labs.

The company aims for SKR to provide Seeker owners with “actual ownership in the platform” and plans to implement linear inflation to reward early stakers.

More information about the SKR token is expected to be unveiled at the Solana Breakpoint Conference, scheduled for December 11-13.
