CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of HE (High Efficiency) PHY capabilities in the mt76 Wi-Fi driver, specifically in the mt7915 module. An attacker could exploit this flaw to cause a NULL pointer dereference, potentially leading to denial of service conditions. Organizations using Linux systems with the mt7915 Wi-Fi driver should prioritize addressing this issue to maintain network stability and security.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: guard HE capability lookups mt7915_mcu_bss_he_tlv() and mt7915_mcu_sta_bfer_tlv() both run after checking HE support, then dereference the HE PHY capability returned by mt76_connac_get_he_phy_cap(). That helper can return NULL when no capability entry matches the vif type. Fetch the capability before appending the TLV and skip the HE-specific setup when no matching capability is available.
