Technical details

A use-after-free (UAF) vulnerability exists in the Wi-Fi driver of multiple Samsung Exynos chipsets (980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000). The root cause is improper synchronization (CWE-362) when accessing a global variable, which allows an attacker to trigger a race condition. By concurrently invoking an ioctl function from multiple threads, a local attacker with low privileges can cause memory corruption. This can lead to local privilege escalation or a complete system crash (denial of service).
