Four-Year-Old Critical Linux Wi-Fi Bug Allows System Compromise

A security researcher with Github recently uncovered a critical security flaw in a Wi-Fi driver for Linux that could enable threat actors to remotely take control of vulnerable machines.

The researcher said that “the vulnerability triggers an overflow, which means it could make Linux crash or if a proper exploit is written (which is not trivial), an attacker could obtain remote code-execution.” The bug has been present in Linux systems for about 4 years. So far no patch has been made available.
