GHSA-583X-9H9H-F6F6

Vulnerability from github – Published: 2025-03-07 09:30 – Updated: 2025-10-29 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

amdkfd: properly free gang_ctx_bo when failed to init user queue

The destructor of a gtt bo is declared as void amdgpu_amdkfd_free_gtt_mem(struct amdgpu_device adev, void mem_obj); 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.

Severity ?

5.5 (Medium)
