Overview

CVE-2024-50096 is a high-severity vulnerability. It was published on November 5, 2024 and has a CVSS 3.1 base score of 7.3 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.3, 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:

nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error

The `nouveau_dmem_copy_one` function ensures that the copy push command is

sent to the device firmware but does not track whether it was executed

successfully.

In the case of a copy error (e.g., firmware or hardware failure), the

copy push command will be sent via the firmware channel, and

`nouveau_dmem_copy_one` will likely report success, leading to the

`migrate_to_ram` function returning a dirty HIGH_USER page to the user.

This can result in a security vulnerability, as a HIGH_USER page that may

contain sensitive or corrupted data could be returned to the user.

To prevent this vulnerability, we allocate a zero page. Thus, in case of

an error, a non-dirty (zero) page will be returned to the user.

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.

How can CyberStrike help with CVE-2024-50096?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2024-50096 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
