Heap-based buffer overflow vulnerability in Windows Routing and Remote Access Service (RRAS) that allows unauthenticated remote attackers to execute arbitrary code over the network with user interaction. This is a critical network-accessible vulnerability affecting Windows systems running RRAS; successful exploitation grants the attacker complete system compromise with high confidentiality, integrity, and availability impact. The CVSS 8.8 score reflects the severity, though real-world exploitation probability and active KEV status would determine if this is actively weaponized.

Local privilege escalation vulnerability in Windows Installer caused by improper access control (CWE-284) that allows an authorized local attacker to elevate privileges without user interaction. The vulnerability affects Windows Installer components across multiple Windows versions and has a CVSS score of 7.8 (High severity).

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.

Memory management vulnerability in Windows Cryptographic Services where memory is not properly released after its effective lifetime, enabling unauthenticated remote code execution. The vulnerability affects Windows cryptographic components and allows network-based attackers to execute arbitrary code with high complexity requirements. While the CVSS score of 8.1 indicates significant severity, exploitation requires specific conditions (high attack complexity), and current status regarding KEV listing, EPSS score, and public POC availability is unknown pending official Microsoft advisory release.
