CVE-2023-20952

Estado: ModificadaMedia (5.5)—

En A2DP_BuildCodecHeaderSbc de a2dp_sbc.cc, existe una posible escritura fuera de límites debida a una comprobación de límites ausente. Esto podría provocar una divulgación local de información sin necesidad de privilegios de ejecución adicionales. No se necesita interacción del usuario para la explotación.Product: AndroidVersions: Android-11 Android-12 Android-12L Android-13Android ID: A-186803518
