The tplg_decode_control_mixer1() function reads the num_channels field from untrusted .tplg data and uses it as a loop bound without validating it against the fixed-size channel array (SND_TPLG_MAX_CHAN). A crafted topology file with an excessive num_channels value can cause out-of-bounds heap writes, leading to a crash."},{"lang":"es","value":"Las versiones de alsa-lib 1.2.2 hasta la 1.2.15.2 inclusive, anteriores al commit 5f7fe33, contienen un desbordamiento de búfer basado en montículo en el decodificador de control del mezclador de topología. La función tplg_decode_control_mixer1() lee el campo num_channels de datos .tplg no confiables y lo utiliza como límite de bucle sin validarlo contra el array de canales de tamaño fijo (SND_TPLG_MAX_CHAN).
