Overview

CVE-2026-68471 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

wifi: ieee80211: validate MLE common info length

ieee80211_mle_common_size() 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 also skipped the length octet when calculating the

minimum common size, and Priority Access MLEs skipped validation of the

advertised common information length.

Account for the Reconfiguration common-info length octet and validate

the advertised common information length for all known MLE types. Keep

unknown-type handling unchanged.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
