CVE-2026-97500 Linux CVE debrief

Who should care

Defenders and system administrators responsible for Linux kernel-based systems, particularly those using the rtw89 driver, should assess exposure and prioritize patching. The vulnerability requires verification and patching to prevent potential out-of-range access issues, particularly for systems using this driver. System administrators should review system configurations and inventory to identify potential exposure and monitor system logs for suspicious  

Why it matters

The Linux kernel vulnerability in the rtw89 driver requires verification and patching to prevent potential out-of-range access issues, particularly for systems using this driver.

• Verify patch application to prevent potential out-of-range access issues.
• Monitor system logs for suspicious activity related to the rtw89 driver.
• Review system configurations and inventory to identify potential exposure.

Technical summary

The Linux kernel's rtw89 driver does not properly check the length of PHY status IE, potentially leading to out-of-range access. This issue has been resolved with patches available. The vulnerability affects systems using the rtw89 driver and requires verification and patching to prevent potential out-of-range access issues. Defenders should prioritize verifying and applying patches for the Linux kernel, particularly for systems using the rtw89 driver, to prevent potential out-of-range access issues. The CVE record and NVD entry provide information on the vulnerability.

Defensive priority

Defenders should prioritize verifying and applying patches for the Linux kernel, particularly for systems using the rtw89 driver, to prevent potential out-of-range access issues.

Recommended defensive actions

• Verify and apply patches for the Linux kernel, particularly for systems using the rtw89 driver.
• Review system configurations and inventory to identify potential exposure.
• Monitor system logs for suspicious activity related to the rtw89 driver.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.

Evidence notes
