CVE-2018-3970
An exploitable memory disclosure vulnerability exists in the 0x222000 IOCTL handler functionality of Sophos HitmanPro.Alert 3.7.6.744.
Does this matter?
Lower severity and a low EPSS score (0.49%). Track it; it rarely justifies an emergency change on its own.
Description
An exploitable memory disclosure vulnerability exists in the 0x222000 IOCTL handler functionality of Sophos HitmanPro.Alert 3.7.6.744. A specially crafted IRP request can cause the driver to return uninitialized memory, resulting in kernel memory disclosure. An attacker can send an IRP request to trigger this vulnerability.
