CVE-2025-23136 Information

Apr 17, 2025 cve

Description

In the Linux kernel the following vulnerability has been resolved:

thermal: int340x: Add NULL check for adev

Not all devices have an ACPI companion fwnode so adev might be NULL. This is similar to the commit cd2fd6eab480 (\platform/x86: int3472: Check for adev == NULL).

Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in int3402_thermal_probe().

Note under the same directory int3400_thermal_probe() has such a check.
