| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a NULL pointer deference in the Linux kernel's ACPICA component. This occurs when memory mappings for operation regions overlap page boundaries, triggering warnings if different page attributes are present. Despite attempts to stop these mappings, the issue persists, leading to a NULL pointer deference when trying to read or write the entire length of the map. The ACPI specification allows mapping across different regions, which resolves the issue.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
