Unpatched Flaws Disclosed in Filesystem Bundled Into Millions of Embedded Devices
runZero disclosed seven vulnerabilities in FatFs, a lightweight filesystem library used in firmware across security cameras, drones, industrial controllers, crypto wallets, and other embedded devices. The flaws affect the library's handling of FAT and exFAT formats commonly found on USB drives and SD cards. FatFs is widely deployed in millions of devices, making the disclosure significant for manufacturers and operators relying on affected firmware versions.
Why it matters: Patch availability and exploitation feasibility should be assessed immediately given the broad deployment of FatFs in critical and consumer devices across multiple verticals.
