Overview

CVE-2024-53063 is a high-severity vulnerability. It was published on November 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:

media: dvbdev: prevent the risk of out of memory access

The dvbdev contains a static variable used to store dvb minors.

The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set

or not. When not set, dvb_register_device() won't check for

boundaries, as it will rely that a previous call to

dvb_register_adapter() would already be enforcing it.

On a similar way, dvb_device_open() uses the assumption

that the register functions already did the needed checks.

This can be fragile if some device ends using different

calls. This also generate warnings on static check analysers

like Coverity.

So, add explicit guards to prevent potential risk of OOM issues.

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.
