Answer in brief
CVE-2026-68311 records a Unknown severity vulnerability in wifi: mt76: mt7925: guard link STA in decap offload. 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: mt76: mt7925: guard link STA in decap offload mt7925_sta_set_decap_offload() iterates over the vif valid_links mask when updating decap offload state for an MLO station. The station may not have a link STA for every valid link of the vif, so mt792x_sta_to_link() can return NULL for a link that belongs to the vif but not to the station. The function currently dereferences mlink before checking whether the link WCID is ready. If mlink is NULL, setting or clearing MT_WCID_FLAG_HDR_TRANS dereferences a NULL pointer. Skip links without a station link before touching mlink->wcid.
