CVE-2025-21842 Information

Mar 08, 2025 cve

Description

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.
