Overview

CVE-2024-49997 is a high-severity vulnerability. It was published on October 21, 2024 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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

net: ethernet: lantiq_etop: fix memory disclosure

When applying padding, the buffer is not zeroed, which results in memory

disclosure. The mentioned data is observed on the wire. This patch uses

skb_put_padto() to pad Ethernet frames properly. The mentioned function

zeroes the expanded buffer.

In case the packet cannot be padded it is silently dropped. Statistics

are also not incremented. This driver does not support statistics in the

old 32-bit format or the new 64-bit format. These will be added in the

future. In its current form, the patch should be easily backported to

stable versions.

Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets

in hardware, so software padding must be 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.
