CVE-2009-3725: Canonical Ubuntu Linux

High severity, CVSS 7.2. EPSS: 0.6% chance of exploitation in the next 30 days.

The connector layer in the Linux kernel before 2.6.31.5 does not require the CAP_SYS_ADMIN capability for certain interaction with the (1) uvesafb, (2) pohmelfs, (3) dst, or (4) dm subsystem, which allows local users to bypass intended access restrictions and gain privileges via calls to functions in these subsystems.

Affected products

• Canonical Ubuntu Linux: version 6.06 only; version 8.04 only; version 8.10 only; version 9.04 only; version 9.10 only
• Linux Linux Kernel: before 2.6.31.5 (fixed in 2.6.31.5)
