CVE-2023-20931

Estado: ModificadaAlta (7.8)—

En avdt_scb_hdl_write_req de avdt_scb_act.cc, existe una posible escritura fuera de límites debida a un desbordamiento de búfer en el montículo (heap). Esto podría dar lugar a una escalada de privilegios local sin que se necesiten privilegios de ejecución adicionales. No es necesaria la interacción del usuario para su explotación.Product: AndroidVersions: Android-11 Android-12 Android-12L Android-13Android ID: A-242535997
