CVE-2024-42112

net: txgbe: free isb resources at the right time

In the Linux kernel, the following vulnerability has been resolved:

net: txgbe: free isb resources at the right time

When using MSI/INTx interrupt, the shared interrupts are still being
handled in the device remove routine, before free IRQs. So isb memory
is still read after it is freed. Thus move wx_free_isb_resources()
from txgbe_close() to txgbe_remove(). And fix the improper isb free
action in txgbe_open() error handling path.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
