CVE-2026-68309

Описание

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: connac: fix possible NULL-pointer deref in mt76_connac_mcu_uni_bss_he_tlv() mt76_connac_get_he_phy_cap routine can theoretically return NULL so check cap pointer before dereferencing it.

A flaw was found in the Linux kernel's mt76 Wi-Fi driver. This vulnerability occurs because the mt76_connac_get_he_phy_cap routine can return a NULL value, which is then dereferenced without proper validation. This can lead to a NULL-pointer dereference, potentially causing a system crash and resulting in a Denial of Service (DoS).

Отчет

This issue affects MediaTek mt76 connac Wi-Fi drivers broadly. mt76_connac_mcu_uni_bss_he_tlv() does not guard NULL from mt76_connac_get_he_phy_cap(). Systems without affected MediaTek Wi-Fi are not affected.
