**Name of the Vulnerable Software and Affected Versions** SecureAge CatchPulse versions prior to 10.9.4 **Description** A heap-based buffer overflow exists in the kernel driver component `saappctl.sys`. A local attacker with low privileges can corrupt kernel memory via IOCTL (Input/Output Control) calls, which are requests sent from user-mode applications to kernel-mode drivers. This flaw allows the attacker to escalate privileges to SYSTEM level, potentially enabling them to disable Endpoint Detection and Response (EDR) systems, terminate security services, or install boot-level rootkits. Additionally, the signed driver could be used in Bring Your Own Vulnerable Driver (BYOVD) attacks to compromise other systems. **Recommendations** Update to version 10.9.4. Add the vulnerable driver `saappctl.sys` to the Windows Defender Application Control (WDAC) blocklist.

**Name of the Vulnerable Software and Affected Versions** VS Revo RevoUninstaller versions 2.5.x through 2.6.x **Description** A heap-based buffer overflow exists in the `IOCtl Handler` function within the `RevoDetector.sys` library of the IOCTL Handler component. This issue requires local access to be exploited. **Recommendations** Upgrade to version 2.7.0.

**Name of the Vulnerable Software and Affected Versions** SecureAge CatchPulse versions prior to 10.9.2 **Description** An issue exists in the IOCTL Handler component within the `saappctl.sys` library. A flaw in an unknown function allows for information disclosure, requiring local access to be exploited. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
