PerformanceTest: Incorrect Permission Assignment for Critical Resource
CVE-2026-80112 is a high-severity incorrect permission assignment for critical resource vulnerability in PerformanceTest from PassMark Software, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 11.1 build 1012 as the first without the flaw, so updating PerformanceTest to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.15% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update PerformanceTest to 11.1 build 1012 or a later version.
- Update BurnInTest to 11.1 build 1000 or a later version.
- Update OSForensics to 11.1 build 1016 or a later version.

Official description
PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain an improper access control vulnerability in the DirectIo64.sys kernel driver that allows unprivileged local users to perform privileged hardware operations by opening a handle to the device object created without a security descriptor. Attackers can issue IOCTLs through the permissive default Windows ACL applied to the device to access restricted hardware operations regardless of privilege or integrity level.

The underlying weakness: Incorrect Permission Assignment for Critical Resource
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
How developers prevent this class of flaw
- When using a critical resource such as a configuration file, check to see if the resource has insecure permissions (such as being modifiable by any regular user), and generate an error or even exit the software if there is a possibility that the resource could have been modified by an unauthorized party.
- Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully defining distinct user groups, privileges, and/or roles. Map these against data, functionality, and the related resources. Then set the permissions accordingly. This will allow you to maintain more fine-grained control over your resources.
- During program startup, explicitly set the default permissions or umask to the most restrictive setting possible. Also set the appropriate permissions during program installation. This will prevent you from inheriting insecure permissions from any user who installs or runs the program.
