A flaw was found in the Linux kernel's mwifiex Wi-Fi driver. When a synchronous command's wait operation is interrupted, the driver can attempt to write data to a memory location that has already been released. This memory corruption can lead to a system crash (kernel panic), resulting in a Denial of Service (DoS).
