7.8 · HIGH

In the Linux kernel, the following vulnerability has been resolved: r8169: Fix possible ring buffer corruption on fragmented Tx packets.

Published Jun 19, 2024CWE-787EPSS 0.25%

Overview

CVE-2024-38586 is a high-severity vulnerability. It was published on June 19, 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:

r8169: Fix possible ring buffer corruption on fragmented Tx packets.

An issue was found on the RTL8125b when transmitting small fragmented

packets, whereby invalid entries were inserted into the transmit ring

buffer, subsequently leading to calls to dma_unmap_single() with a null

address.

This was caused by rtl8169_start_xmit() not noticing changes to nr_frags

which may occur when small packets are padded (to work around hardware

quirks) in rtl8169_tso_csum_v2().

To fix this, postpone inspecting nr_frags until after any padding has been

applied.

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.
