Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> amdkfd: properly free gang_ctx_bo when failed to init user queue<br /> <br /> The destructor of a gtt bo is declared as<br /> void amdgpu_amdkfd_free_gtt_mem(struct amdgpu_device *adev, void **mem_obj);<br /> Which takes void** as the second parameter.<br /> <br /> GCC allows passing void* to the function because void* can be implicitly<br /> casted to any other types, so it can pass compiling.<br /> <br /> However, passing this void* parameter into the function&amp;#39;s<br /> execution process(which expects void** and dereferencing void**)<br /> will result in errors.
