Deskripsi (NVD)

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain an information disclosure vulnerability in DirectIo64.sys that allows unauthenticated local attackers to dump complete physical memory contents by supplying a caller-controlled file path to an exposed IOCTL. Attackers can issue a single IOCTL call to trigger the driver to iterate all physical memory ranges via MmGetPhysicalMemoryRanges and map each page through ZwMapViewOfSection on the PhysicalMemory section object, writing a full RAM image to an attacker-specified path in the SYSTEM context, bypassing user-mode ACLs and exposing LSASS working set, process memory, and cryptographic material from all running processes.
