A remote user with Wi-Fi connection could use this flaw to crash the system." ],
  "statement" : "A vulnerability in the Marvell mwifiex driver (mwifiex, Marvell Wi-Fi) allows malformed over-the-air frames to trigger out-of-bounds reads and an integer underflow in the RX path, which can crash the kernel or drop packets. Remote code execution is highly unlikely — the flaw manifests as OOB reads / length miscalculations (leading to OOPS/panic or DoS), not as a controllable arbitrary-write or instruction pointer corruption, so an attacker cannot reliably gain code execution from this bug.\nThis issue only affects systems running the mwifiex driver; if the system does not use Marvell’s mwifiex module there is no exposure.",
