In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix an integer overflow in aie2_query_ctx_status_array() The unpublished smatch static checker reported a warning. drivers/accel/amdxdna/aie2_pci.c:904 aie2_query_ctx_status_array() warn: potential user controlled sizeof overflow 'args->num_element * args->element_size' '1-u32max(user) * 1-u32max(user)' Even this will not cause a real issue, it is better to put a reasonable limitation for element_size and num_element. Add condition to make sure the input element_size <= 4K and num_element <= 1K.
