CVE-2023-53237: 
Linux Kernel vulnerability analysis and mitigation

CVE-2023-53237 is a vulnerability discovered in the Linux kernel, specifically affecting the AMD GPU driver (amdgpu). The issue was identified in September 2025 and involves an improper handling of interrupt requests in the gmcv110hwfini function (NVD).

The vulnerability stems from the mishandling of the amdgpuirqput function call in gmcv110hwfini. The core issue relates to the gmc.eccirq being enabled by firmware per IFWI setting, where the host driver lacks privileges to enable/disable the interrupt. This leads to a meaningless use of the amdgpuirqput function in gmcv110hw_fini, resulting in a call trace (NVD).

The vulnerability can cause system instability and potential call traces in systems using AMD GPUs with the affected driver versions. This primarily affects the system's graphics and memory controller functionality (NVD).

The issue has been addressed through patches in various Linux distributions. Ubuntu has released security updates for multiple kernel versions including 20.04 LTS, with fixes being deployed across different kernel variants such as AWS, GCP, and Oracle (Ubuntu Security).
