CVE-2011-0521: Linux Kernel

High severity, CVSS 7.2. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: before 2.6.38 (fixed in 2.6.38); version 2.6.38 only
