Overview

CVE-2024-42112 is a high-severity vulnerability. It was published on July 30, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
