Name of the Vulnerable Software and Affected Versions Accops HyWorks DVM Tools versions prior to 3.3.1.105

Description An Integer Overflow issue exists, allowing local attackers to execute arbitrary code in kernel mode or cause a denial of service via specially crafted I/O Request Packets. The IOCTL Handler 0x22005B is affected, potentially leading to memory corruption and OS crashes.

Recommendations For versions prior to 3.3.1.105, update to version 3.3.1.105 or later to resolve the issue. As a temporary workaround, consider restricting access to the IOCTL Handler 0x22005B to minimize the risk of exploitation.
