CVE-2011-0521

Priority
Description
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.
Ubuntu-Description
Dan Carpenter discovered that the TTPCI DVB driver did not check certain
values during an ioctl. If the dvb-ttpci module was loaded, a local
attacker could exploit this to crash the system, leading to a denial of
service, or possibly gain root privileges.
