CVE-2026-93116 Linux CVE debrief
A high-severity vulnerability was resolved in the Linux kernel, specifically in the platform/x86: asus-wmi module. The vulnerability involves resource leaks on probe failure, which could lead to various defensive consequences if left unaddressed. This issue arises from incorrectly ordered error path labels in the asus_wmi_add() function. Defenders and system administrators responsible for Linux kernel-based systems, especially those utilizing the platform/x86: asus-wmi module, should assess their exposure and prioritize patching. The vulnerability has a CVSS score of 7 and is considered HIGH severity.

Who should care
Defenders and system administrators responsible for Linux kernel-based systems, especially those utilizing the platform/x86: asus-wmi module, should assess their exposure and prioritize patching.
Why it matters
A high-severity vulnerability in the Linux kernel's platform/x86: asus-wmi module could lead to resource leaks on probe failure, emphasizing the need for prompt patching and system review.
- Verification of patch application is necessary to prevent potential resource leaks.
- System administrators should review and update their inventory to identify potentially affected systems.
- Monitoring system logs for suspicious activity related to the affected module is recommended.
Technical summary
The vulnerability is caused by incorrectly ordered error path labels in the asus_wmi_add() function, leading to resource leaks on probe failure. This could result in various defensive consequences if left unaddressed. The vulnerability has a CVSS score of 7 and is considered HIGH severity. The Linux kernel patch for the platform/x86: asus-wmi module resolves the resource leaks on probe failure by reordering error path labels to match the exact reverse order of resource allocations. Defenders should prioritize verifying and applying patches for this vulnerability, especially for systems utilizing the affected Linux kernel module.
Defensive priority
Defenders should prioritize verifying and applying patches for this vulnerability, especially for systems utilizing the affected Linux kernel module.
Recommended defensive actions
- Verify and apply patches for the Linux kernel, specifically for the platform/x86: asus-wmi module.
- Review system configurations and inventory to identify potential exposure.
- Monitor system logs for suspicious activity related to the affected module.
- Perform thorough vulnerability assessments to identify potentially affected systems.
- Implement compensating controls for exposed systems while remediation is scheduled and verified.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
- Review and update incident response plans to address potential exploitation of this vulnerability.
