Answer in brief
CVE-2026-68406 records a Unknown severity vulnerability in wifi: cfg80211: validate PMSR FTM preamble range. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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]
