Samsung Exynos Processors Wi-Fi Driver Double Free Vulnerability

A double free vulnerability has been identified in the Wi-Fi driver of Samsung Mobile Processor and Wearable Processor Exynos 980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000. The vulnerability arises from improper synchronization of a global variable, which creates a race condition that an attacker can exploit by concurrently invoking an ioctl function from multiple threads.

Impact

Exploitation of this vulnerability leads to a double free condition, which can commonly result in memory corruption and potentially allow for arbitrary code execution.
