CVE-2010-3296: Canonical Ubuntu Linux

Low severity, CVSS 2.1. EPSS: 0.4% chance of exploitation in the next 30 days.

The cxgb_extension_ioctl function in drivers/net/cxgb3/cxgb3_main.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a CHELSIO_GET_QSET_NUM ioctl call.
