Severity CVSS v4.0:
Pending analysis
Type:
CWE-416 Use After Free
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: txgbe: free isb resources at the right time<br /> <br /> When using MSI/INTx interrupt, the shared interrupts are still being<br /> handled in the device remove routine, before free IRQs. So isb memory<br /> is still read after it is freed. Thus move wx_free_isb_resources()<br /> from txgbe_close() to txgbe_remove(). And fix the improper isb free<br /> action in txgbe_open() error handling path.
