CVE-2023-53388:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2023-53388 is a vulnerability discovered in the Linux kernel's DRM (Direct Rendering Manager) MediaTek driver. The issue was identified in the mtkdrmbind() function, where a dangling pointer condition could occur in the error handling path. The vulnerability was disclosed on September 18, 2025 (NVD).
Technical details
The vulnerability occurs when mtkdrmbind() fails, causing drmdevput() to be called, which destroys the drmdevice object. However, a pointer to this destroyed object was still being held in the private object. If a suspend operation was triggered at this point through mtkdrmsysprepare(), the dangling pointer would be passed to DRM, resulting in a system panic (NVD).
Impact
When exploited, this vulnerability can lead to a system panic due to the use of a dangling pointer, potentially causing system instability or denial of service conditions (NVD).
Mitigation and workarounds
The issue has been resolved by cleaning the pointer when destroying the object in the error path, preventing the dangling pointer condition from occurring (NVD).
