A mechanism for wirelessly updating an FPGA that is built into a wireless mobile or another wireless electronic device is described herein. The wireless update may be performed responsive to detecting a hardware vulnerability or another hardware issue in the mobile device. When the hardware vulnerability or another hardware issue is detected, the mechanism may identify a fix for the hardware vulnerability. A fix may be a particular FPGA configuration update known to fix the issue. The configuration update to the FPGA is received and the current FPGA configuration is overwritten with data from the configuration update. A determination is made that the hardware vulnerability no longer exists.
