AI-suggested
A patch is available and should be applied by updating the Linux kernel to version 7.0.0 or later as specified in the vendor advisory. After applying the update, a system reboot is required. No additional mitigation actions are necessary as the issue is fixed by the official update.
Description
A vulnerability in the Linux kernel's airoha network driver was resolved by moving the ndesc initialization to the end of the airoha_qdma_init_tx() function. The flaw caused a NULL pointer dereference if queue entry list allocation failed in the airoha_qdma_init_tx_queue routine, potentially leading to a denial of service. This issue was fixed in Linux kernel versions 7.0.0 and later. The vulnerability has a medium severity score of 5.5 and does not impact confidentiality or integrity but affects availability. A patch is available and should be applied to affected systems.
