| Subject: CVE-2025-23136: thermal: int340x: Add NULL check for adev |
| |
| 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. |
| |
| [ rjw: Subject edit, added Fixes: ] |
| |
| The Linux kernel CVE team has assigned CVE-2025-23136 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
