Summary

When converting a uintptr to an unsafe.Pointer I get the error G115: integer overflow conversion uintptr -> unsafe.Pointer, even though these can be safely converted (see https://pkg.go.dev/unsafe#Pointer "A uintptr can be converted to a Pointer.").

Steps to reproduce the behavior

package main

func main() {
	i := uintptr(123)
	p := unsafe.Pointer(i)
	_ = p
}

gosec version

Expected behavior

Passes without errors.

Throws error G115: integer overflow conversion uintptr -> unsafe.Pointer
