CVE-2026-68406
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: validate PMSR FTM preamble range PMSR FTM request parsing accepts preamble values outside the enumerated nl80211 preamble range. Reject out-of-range values before using them in the parser capability bit test using the policy. [drop unnecessary check]
Executive briefing
The source record describes: In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: validate PMSR FTM preamble range PMSR FTM request parsing accepts preamble values outside the enumerated nl80211 preamble range. Reject out-of-range values before using them in the parser capability bit test using the policy. [drop unnecessary check] The practical risk depends on whether an affected product/version is present, reachable and configured in an exploitable way. Review the affected-product evidence and linked vendor advisories before assigning exposure status.
Evidence confidence: Limited Evidence-derived, not an exploitability verdict

No CVSS vector is currently available in the source record.
Technical explanation & impact
The technical mechanism is not expanded beyond the source description unless a referenced advisory supplies additional evidence. Read the linked vendor/CERT advisories for root-cause detail.
Potential impact must be interpreted from the published CVSS impact metrics and the affected component. A CVSS impact score is not proof that a particular asset is exploitable.
Affected products and versions
NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.
Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
