kernel: net: airoha: Move ndesc initialization at end of airoha_qdma_init_tx()
    </Bugzilla>
    <CWE>CWE-824</CWE>
    <Details xml:lang="en:us" source="Mitre">
In the Linux kernel, the following vulnerability has been resolved:

net: airoha: Move ndesc initialization at end of airoha_qdma_init_tx()

If queue entry list allocation fails in airoha_qdma_init_tx_queue routine,
airoha_qdma_cleanup_tx_queue() will trigger a NULL pointer dereference
accessing the queue entry array. The issue is due to the early ndesc
initialization in airoha_qdma_init_tx_queue(). Fix the issue moving ndesc
initialization at end of airoha_qdma_init_tx routine.
    </Details>
    <Details xml:lang="en:us" source="Red Hat">
A flaw was found in the Linux kernel, specifically within the airoha network driver. This vulnerability arises from an issue where a variable (ndesc) is initialized too early in the airoha_qdma_init_tx_queue routine. If a queue entry list allocation fails, this premature initialization can lead to a NULL pointer dereference, which could allow a local attacker to trigger a system crash. This results in a Denial of Service (DoS), making the system unavailable.
