CVE-2011-0521

[Leann Ogasawara]

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.
