Doc Text:
A vulnerability was found in the Linux kernel's `txgbe` driver involving uninitialized `num_q_vectors` when using MSI/INTx interrupts. This can lead to kernel panics during the allocation of queue vectors due to the use of undefined values. This issue was resolved by ensuring `num_q_vectors` is properly initialized, thereby preventing system crashes and enhancing overall stability.

Description OSIDB Bzimport 2024-07-30 08:31:23 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: txgbe: initialize num_q_vectors for MSI/INTx interrupts

When using MSI/INTx interrupts, wx->num_q_vectors is uninitialized.
Thus there will be kernel panic in wx_alloc_q_vectors() to allocate
queue vectors.
