CVE-2026-68471 Linux CVE debrief
The Linux kernel has a vulnerability related to wifi MLE common info length validation. This issue affects Linux kernel wifi systems, particularly those using ieee80211_mle_common_size() and ieee80211_mle_size_ok() functions. The vulnerability allows for potential wifi MLE-related issues due to improper validation of the advertised common information length for all known MLE types, including Reconfiguration MLEs and Priority Access MLEs. Linux kernel maintainers, wifi developers, and organizations using Linux-based wifi systems should review and address this vulnerability. They should verify kernel versions and wifi MLE usage in inventory, and monitor for potential wifi MLE-related issues. This vulnerability requires defensive review and patching to prevent potential wifi MLE-related issues in Linux kernel wifi systems. Limited evidence suggests that defensive review and patching are necessary to address this vulnerability.

Who should care
Linux kernel maintainers, wifi developers, and organizations using Linux-based wifi systems should review and address this vulnerability. They should verify kernel versions and wifi MLE usage in inventory, and monitor for potential wifi MLE-related issues. This vulnerability requires defensive review and patching to prevent potential wifi MLE-related issues in Linux kernel wifi systems.
Technical summary
The Linux kernel has a vulnerability related to wifi MLE common info length validation. The ieee80211_mle_common_size() function uses the first common-info octet as the common information length for all known MLE types. However, ieee80211_mle_size_ok() only validates that octet for Basic, Probe Request, and TDLS MLEs. Reconfiguration MLEs and Priority Access MLEs also require validation. This vulnerability affects Linux kernel wifi systems, requiring review and patching.
Defensive priority
Linux kernel wifi MLE common info length validation vulnerability requires defensive review and patching.
Recommended defensive actions
- Review Linux kernel patch notes for wifi MLE common info length validation fix
- Verify kernel version and wifi MLE usage in inventory
- Monitor for potential wifi MLE-related issues
- Perform a thorough review of wifi MLE usage in Linux kernel systems
- Implement compensating controls for exposed systems while remediation is scheduled and verified
- Track exceptions and retest remediated assets
- Review source references for kernel patch and affected scope
Evidence notes
Primary official records indicate a Linux kernel vulnerability related to wifi MLE common info length validation. Evidence is limited, requiring further review of kernel patch notes and source references for affected scope and remediation details. The CVE record was published on 2026-08-15T06:20:05.433Z and has not been modified since then. Limited evidence suggests Linux kernel maintainers and wifi developers should verify kernel versions and wifi MLE usage in inventory.
