CVE-2011-2492: The bluetooth subsystem in the Linux kernel before 3.0-rc4 does not properly initialize certain data struct...

Security readout for executives and security teams

A flaw in older Linux Bluetooth code could let a local user read small amounts of kernel memory. That may expose sensitive data, but the bundle does not show remote exploitation or active abuse. Business urgency depends on whether legacy Linux systems with Bluetooth and local user access remain in service. Likely exposure is legacy Linux systems running kernels before 3.0-rc4, or vendor kernels missing the backported fix, with Bluetooth stack available and local user access. Systems without Bluetooth support or without untrusted local users have reduced practical exposure. Handle during legacy Linux remediation unless the environment still runs unfixed kernels with local user access. This is not supported as actively exploited in the bundle, but kernel memory disclosure should not remain unresolved on supported systems. Mitigation focus: Update affected Linux kernels to a fixed vendor-supported package.; Confirm vendor backports address CVE-2011-2492 or the referenced Bluetooth fix.; Review RHSA-2011:0927 if managing affected Red Hat systems..
