This vulnerability affects the Wi-Fi driver in Samsung Exynos processors including models 980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000. The root cause is improper synchronization on a global variable, which leads to a double free memory error. An attacker can exploit this by invoking an ioctl function concurrently from multiple threads, triggering a race condition. The CVSS 3.1 score is 7.0, indicating high severity with local attack vector, high attack complexity, low privileges required, no user interaction, and impacts on confidentiality, integrity, and availability. The vulnerability is classified under CWE-362 (Race Condition). No known exploits in the wild or patch information is currently available.

Successful exploitation can result in a double free condition causing potential memory corruption, which may lead to denial of service or arbitrary code execution with elevated privileges on affected devices. The vulnerability impacts confidentiality, integrity, and availability of the system. However, exploitation requires local access with low privileges and high attack complexity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit local access to affected devices and avoid running untrusted code that could invoke ioctl calls concurrently. Monitor vendor channels for updates and apply patches promptly once available.
