What to do
AI-suggested
The current workaround is to skip GPUs with MES when using the debugfs hang_hws interface. Users should apply the Linux kernel update that includes this fix once available. Since this is a kernel-level issue, upgrading to the fixed kernel version when released is recommended. No other specific mitigations are indicated.
Description
A vulnerability in the Linux kernel's drm/amdkfd component related to the debugfs hang_hws interface causes a kernel crash due to a NULL pointer dereference when handling GPUs with MES (Micro-Engine Scheduler). The issue arises because the dqm->packet_mgr is not set up for the MES path, leading to a crash during GPU reset tests. The current mitigation is to skip GPUs with MES for this debugfs interface until proper support is implemented.
