- Summary
- amdkfd: properly free gang_ctx_bo when failed to init user queue
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
amdkfd: properly free gangctxbo when failed to init user queue
The destructor of a gtt bo is declared as void amdgpuamdkfdfreegttmem(struct amdgpudevice *adev, void memobj); Which takes void as the second parameter.
GCC allows passing void* to the function because void* can be implicitly casted to any other types, so it can pass compiling.
However, passing this void* parameter into the function's execution process(which expects void* and dereferencing void*) will result in errors.
