CVE-2022-50524:
Linux Kernel vulnerability analysis and mitigation
Overview
In the Linux kernel, a vulnerability was identified and resolved in the iommu/mediatek component. The issue involves failing to check the return value after calling platform_get_resource(), which could lead to a null pointer dereference in resource_size(). This vulnerability is tracked as CVE-2022-50524 (NVD).
Technical details
The vulnerability exists in the MediaTek IOMMU driver implementation where the code fails to properly validate the return value of platform_get_resource(). Since platform_get_resource() may return a NULL pointer, the lack of validation could result in a null pointer dereference when calling resource_size() with the unchecked value (NVD).
Impact
If exploited, this vulnerability could lead to a null pointer dereference, potentially causing a system crash or denial of service condition on affected Linux systems using the MediaTek IOMMU driver (NVD).
Mitigation and workarounds
The vulnerability has been resolved in the Linux kernel through a patch that implements proper return value checking after calling platform_get_resource() before passing the value to resource_size() (NVD).
