AI description
CVE-2025-30388 is a heap-based buffer overflow vulnerability found in the Windows Win32K - GRFX component. It allows an unauthorized attacker with local access to execute code on a vulnerable system. The vulnerability stems from the Win32K GRFX subsystem's inadequate validation of user-supplied input size during graphical rendering, which can lead to memory corruption and arbitrary code execution within the kernel context. The vulnerability affects multiple Microsoft products, including various versions of Windows Server (2008 through 2025), Windows 10, Windows 11, and Microsoft Office installations. Microsoft has released patch KB5058384 to address this vulnerability. However, some users have reported issues with the patch not properly updating DLLs.
