CVE-2024-27075
Estado: AnalizadaAlta (7.8)—
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: dvb-frontends: evita advertencias de desbordamiento de pila con clang. Un parche anterior solucionó un problema de KASAN en stv0367, ahora apareció un problema similar con clang: drivers/media/dvb- frontends/stv0367.c:1222:12: error: el tamaño del marco de pila (3624) excede el límite (2048) en 'stv0367ter_set_frontend' [-Werror,-Wframe-larger-than] 1214 | static int stv0367ter_set_frontend(struct dvb_frontend *fe) Vuelva a trabajar la función stv0367_writereg() para que sea más simple y marque ambas funciones de acceso a registros como noinline_for_stack para que las estructuras temporales i2c_msg no se dupliquen en la pila cuando KASAN_STACK esté habilitado.
