CISA Known Exploited Vulnerabilities Directory

Microsoft Win32k contains a privilege escalation vulnerability when the Win32k component fails to properly handle objects in memory. Successful exploitation allows an attacker to execute code in kernel mode.

Microsoft Win32k contains an unspecified vulnerability due to it failing to properly handle objects in memory causing privilege escalation. Successful exploitation allows an attacker to run code in kernel mode.

Microsoft Win32k contains a privilege escalation vulnerability due to the component failing to properly handle objects in memory. Successful exploitation allows an attacker to run code in kernel mode.

Microsoft Win32k fails to properly handle objects in memory causing privilege escalation. Successful exploitation allows an attacker to run code in kernel mode.

Microsoft Windows Error Reporting (WER) contains a privilege escalation vulnerability due to the way it handles files, allowing for code execution in kernel mode.

Microsoft Windows Common Log File System (CLFS) driver improperly handles objects in memory which can allow for privilege escalation.

Microsoft Windows contains an unspecified vulnerability due to the way ws2ifsl.sys (Winsock) handles objects in memory, allowing for privilege escalation. Successful exploitation allows an attacker to execute code with elevated privileges.

Microsoft Internet Explorer contains a memory corruption vulnerability in how the scripting engine handles objects in memory. Successful exploitation allows for remote code execution in the context of the current user.

Microsoft Internet Explorer contains a memory corruption vulnerability which can allow for remote code execution in the context of the current user.

Microsoft Windows CryptoAPI (Crypt32.dll) contains a spoofing vulnerability in the way it validates Elliptic Curve Cryptography (ECC) certificates. An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source. A successful exploit could also allow the attacker to conduct man-in-the-middle attacks and decrypt confidential information on user connections to the affected software. The vulnerability is also known under the moniker of CurveBall.
