- drm/amdgpu: Fix a null pointer access when the smc_rreg pointer is NULL
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix a null pointer access when the smc_rreg pointer is NULL
In certain types of chips, such as VEGA20, reading the amdgpuregssmc file could result in an abnormal null pointer access when the smc_rreg pointer is NULL. Below are the steps to reproduce this issue and the corresponding exception log:
- Navigate to the directory: /sys/kernel/debug/dri/0
- Execute command: cat amdgpuregssmc
