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
