The Malwarebytes Anti-Exploit installed on the remote Windows host is a version prior to 1.05.1.1014. It is, therefore, affected by a out-of-bounds read flaw in the ‘mbae.sys’ driver when handling certain IOCTL calls. A local attacker can exploit this to cause access of invalid memory, resulting in a denial of service
