Descriptions
The dvb_ca_ioctl function in drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel before 2.6.38-rc2 does not check the sign of a certain integer field, which allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a negative value.
La función dvb_ca_ioctl function en drivers/media/dvb/ttpci/av7110_ca.c para el kernel Linux anterior a v2.6.38-rc2 no comprueba el signo de un campo entero determinado, lo que permite a usuarios locales causar una denegación de servicio (corrupción de memoria) o posiblemente tener un impacto no especificado a través de un valor negativo.
