What to do

AI-suggested

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.

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().
