Heap-based buffer overflow vulnerability in the Windows Common Log File System (CLFS) Driver that allows local authenticated attackers to achieve privilege escalation with high confidence of exploitation. The vulnerability affects Windows systems with the CLFS driver enabled and requires local access with standard user privileges; successful exploitation grants complete system compromise including code execution at SYSTEM level. While no public POC is confirmed in available intelligence, the straightforward nature of heap overflows and the high CVSS score (7.8) with low attack complexity indicate active research interest and potential for rapid weaponization.

Use-after-free vulnerability in the Windows Win32K graphics subsystem (GRFX component) that allows a locally authenticated attacker to achieve arbitrary code execution and privilege escalation without user interaction. The vulnerability affects Windows systems with affected Win32K versions and carries a CVSS score of 7.8 (high severity). Given the local attack vector requirement and the need for prior authentication, real-world exploitation is constrained to insider threats or attackers who have already achieved initial access; however, the severity of the impact (complete system compromise) makes this a critical priority for patching.
