CVE-2026-80119: External Control of File Name or Path in PassMark Software PerformanceTest
Description
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.

Technical Analysis
CVE-2026-80119 is an information disclosure vulnerability in PassMark PerformanceTest (and related products) prior to version 11.1 builds specified, involving the DirectIo64.sys driver. An unauthenticated local attacker can exploit an exposed IOCTL by providing a controlled file path, triggering the driver to iterate all physical memory ranges and map each page to write a complete physical memory dump to a path under the attacker's control. This occurs in the SYSTEM context, bypassing user-mode ACLs and exposing sensitive data including LSASS memory, process memory, and cryptographic material from all running processes.
Potential Impact
Successful exploitation allows local attackers to obtain a complete physical memory dump with SYSTEM privileges, exposing sensitive information such as LSASS working set, process memory, and cryptographic keys. This can lead to further privilege escalation, credential theft, and compromise of system security.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict local access to trusted users only and monitor for suspicious local activity involving the vulnerable driver.
