Linux hwe edge: In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: Fix NULL pointer dereference in mt7996_init_tx_queues() When… (CVE-2026-80632)
Description
A NULL pointer dereference vulnerability in the Linux kernel's mt7996 WiFi driver was fixed. The issue occurs in the function mt7996_init_tx_queues() when specific kernel configurations are enabled and the Airoha NPU SoC is detected. This dereference could lead to a low-severity fault in affected systems. The fix involves passing the WED pointer correctly from mt7996_dma_init().

Technical Analysis
The Linux kernel mt7996 WiFi driver had a NULL pointer dereference vulnerability in the mt7996_init_tx_queues() function. This occurs when both MT76_NPU and CONFIG_NET_MEDIATEK_SOC_WED configurations are enabled and the Airoha NPU SoC is detected by the mt76 driver. The function dereferenced a NULL WED pointer, causing a potential fault. The issue was resolved by ensuring the WED pointer is always passed from mt7996_dma_init(), preventing the NULL dereference.
Potential Impact
The vulnerability can cause a NULL pointer dereference, which may lead to a kernel fault or crash under the specified conditions. The severity is assessed as low, indicating limited impact and no known exploitation in the wild.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to address this issue. Users should update to the patched kernel versions that include this fix. Since this is a kernel-level vulnerability, applying the official kernel update from the Linux distribution vendor is the recommended remediation.
