A critical vulnerability in SD Express memory cards, called DaMAgeCard, has been uncovered, enabling attackers to exploit the PCIe interface for direct access to system memory. Discovered by Positive Technologies, this flaw can potentially give attackers unauthorized access to system memory, bypassing typical software defenses.
The DaMAgeCard exploit leverages the PCIe interface within SD Express memory cards to perform Direct Memory Access (DMA) attacks. By exploiting the privileged access that PCIe provides, attackers can bypass traditional software-based security mechanisms such as antivirus programs or OS-level protections. Once connected to a vulnerable system, the compromised SD Express card can directly interact with the system's memory.
