CVE-2021-42687

Name of the Vulnerable Software and Affected Versions Accops HyWorks Windows Client versions prior to 3.2.8.200

Description A Buffer 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 vulnerable, potentially leading to memory corruption and OS crash.
