The MITRE CVE dictionary describes this issue as:
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.
Red Hat is aware of this issue and is tracking it via the following bug:
This issue did not affect the version of the Linux kernel as shipped with Red Hat Enterprise Linux 3 as it did not include support for ULE (Unidirectional Lightweight Encapsulation). We have included a fix for this issue in Red Hat Enterprise Linux 4, 5 and Red Hat Enterprise MRG however the affected module is not build by default.
