Description OSIDB Bzimport 2024-07-30 08:31:08 UTC 
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.
