This vulnerability impacts the following Exynos models: 980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000. The root cause is an improper synchronization on a global variable within the driver, leading to a potential use-after-free scenario. An attacker can exploit this vulnerability by triggering a race condition through concurrent invocation of an \u003ccode\u003eioctl\u003c/code\u003e function from multiple threads. Successful exploitation can lead to memory corruption, arbitrary code execution, and ultimately, device compromise. This vulnerability poses a significant risk to devices using the affected Exynos chipsets, including smartphones and wearable devices.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains initial access to the target device, which could be through a malicious application installed by the user.\u003c/li\u003e\n\u003cli\u003eThe malicious application creates multiple threads to concurrently access the Wi-Fi driver.\u003c/li\u003e\n\u003cli\u003eEach thread invokes the vulnerable \u003ccode\u003eioctl\u003c/code\u003e function within the Wi-Fi driver.\u003c/li\u003e\n\u003cli\u003eDue to the lack of proper synchronization, a race condition occurs when accessing a global variable.\u003c/li\u003e\n\u003cli\u003eOne thread frees the memory associated with the global variable, while another thread continues to access it.\u003c/li\u003e\n\u003cli\u003eThe second thread attempts to use the freed memory, resulting in a use-after-free condition.\u003c/li\u003e\n\u003cli\u003eThe use-after-free condition leads to memory corruption, potentially allowing the attacker to overwrite critical data structures.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the memory corruption to gain arbitrary code execution within the context of the Wi-Fi driver, potentially leading to full device compromise.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2025-54602 can lead to a range of severe consequences. An attacker could potentially gain arbitrary code execution on the affected device.
