CVE-2025-24983 is an elevation-of-privilege vulnerability in the Windows Win32 Kernel Subsystem caused by a use-after-free condition. The flaw allows a locally authenticated attacker with low privileges to trigger memory corruption in kernel context and elevate privileges. Microsoft assessed exploitation as requiring the attacker to win a race condition, which increases attack complexity, but successful exploitation can result in execution with SYSTEM privileges. The vulnerability was reported as exploited in the wild at the time of disclosure.
