CVE-2026-43485

Description

A flaw was found in the Linux kernel's nouveau/gsp module. This issue involved the frequent triggering of diagnostic WARN_ON messages during ACPI (Advanced Configuration and Power Interface) probes. While these warnings were considered largely benign, their persistent appearance indicated an unnecessary diagnostic output. The flaw has been resolved by removing these superfluous WARN_ON calls, improving system stability and reducing log noise.

Understanding the Weakness (CWE)

Availability

Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Other)

Log files can become so large that they consume excessive resources, such as disk and CPU, which can hinder the performance of the system.

Non-Repudiation

Technical Impact: Hide Activities

Logging too much information can make the log files of less use to forensics analysts and developers when trying to diagnose a problem or recover from an attack.

Non-Repudiation

Technical Impact: Hide Activities

If system administrators are unable to effectively process log files, attempted attacks may go undetected, possibly leading to eventual system compromise.
