CVE-2011-0521

Published: 2 February 2011

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.

From the Ubuntu Security Team

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.
