The return value from gfx::SourceSurfaceSkia::Map() wasnt being verified which could have potentially lead to a null pointer dereference. This vulnerability affects Firefox < 110.
The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
