Overview

CVE-2023-53310 is a medium-severity vulnerability. It was published on September 16, 2025 and has a CVSS 3.1 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.7, rated MEDIUM. 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:

power: supply: axp288_fuel_gauge: Fix external_power_changed race

fuel_gauge_external_power_changed() dereferences info->bat,

which gets sets in axp288_fuel_gauge_probe() like this:

info->bat = devm_power_supply_register(dev, &fuel_gauge_desc, &psy_cfg);

As soon as devm_power_supply_register() has called device_add()

the external_power_changed callback can get called. So there is a window

where fuel_gauge_external_power_changed() may get called while

info->bat has not been set yet leading to a NULL pointer dereference.

Fixing this is easy. The external_power_changed callback gets passed

the power_supply which will eventually get stored in info->bat,

so fuel_gauge_external_power_changed() can simply directly use

the passed in psy argument which is always valid.

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.
