The bt_sock_recvmsg function in net/bluetooth/af_bluetooth.c in the Linux kernel before 3.9-rc7 does not properly initialize a certain length variable, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call.

Security readout for executives and security teams

CVE-2013-3224 is a Linux kernel information leak in Bluetooth socket handling. A local user could cause kernel stack memory to be returned, potentially exposing sensitive data. The source bundle does not show active exploitation or remote attack capability. Exposure is most relevant to Linux systems running kernels before 3.9-rc7 or vendor kernels lacking the backported fix, especially where untrusted users or workloads can execute locally. Treat as routine but real kernel hygiene. Patch in normal maintenance windows, with higher priority for shared servers, hosted environments, and systems where local users are not fully trusted. Mitigation focus: Apply kernel updates from the relevant Linux distribution advisory.; Confirm the kernel includes the upstream fix or vendor backport.; Prioritize multi-user hosts and systems running untrusted workloads..
