Summary
Improper access control in the PCTCore64.sys Windows kernel driver from PC Tools Internet Security allows user-mode processes to access the PCTCoreDriver WDM device interface and invoke privileged IOCTL handlers. A local attacker with the ability to access or load the affected driver can exploit this vulnerability to perform sensitive and privileged operations on the target system.
