CVE-2024-26926
Estado: ModificadaMedia (5.5)—
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Binder: verifique la alineación de desplazamiento en binder_get_object() El commit 6d98eb95b450 ("binder: evite posibles fugas de datos al copiar txn") introdujo cambios en la forma en que se copian los objetos de Binder. Al hacerlo, eliminó involuntariamente una verificación de alineación de desplazamiento realizada mediante llamadas a binder_alloc_copy_from_buffer() -> check_buffer().
Leer descripción completaMostrar menos
Estas llamadas fueron reemplazadas en binder_get_object() con copy_from_user(), por lo que ahora se necesita aquí una verificación explícita de alineación de desplazamiento. Esto evita complicaciones posteriores cuando el desenrollado de los objetos se vuelve más difícil. Vale la pena señalar que esta verificación existía antes de el commit 7a67a39320df ("carpeta: agregar función para copiar el objeto de carpeta del búfer"), probablemente eliminada debido a la redundancia en ese momento.
