CVE-2009-3001: Canonical Ubuntu Linux

Medium severity, CVSS 4.9. EPSS: 1% chance of exploitation in the next 30 days.

The llc_ui_getname function in net/llc/af_llc.c in the Linux kernel 2.6.31-rc7 and earlier does not initialize a certain data structure, which allows local users to read the contents of some kernel memory locations by calling getsockname on an AF_LLC socket.

Affected products

• Canonical Ubuntu Linux: version 6.06 only; version 8.04 only; version 8.10 only; version 9.04 only
• Linux Linux Kernel: before 2.6.31 (fixed in 2.6.31); version 2.6.31 only
