Overview

CVE-2023-53003 is a high-severity vulnerability. It was published on March 27, 2025 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:

EDAC/qcom: Do not pass llcc_driv_data as edac_device_ctl_info's pvt_info

The memory for llcc_driv_data is allocated by the LLCC driver. But when

it is passed as the private driver info to the EDAC core, it will get freed

during the qcom_edac driver release. So when the qcom_edac driver gets probed

again, it will try to use the freed data leading to the use-after-free bug.

Hence, do not pass llcc_driv_data as pvt_info but rather reference it

using the platform_data pointer in the qcom_edac driver.

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.
