Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.9-rc7

Description The issue allows local users to obtain sensitive information from kernel stack memory. This is due to the bt sock recvmsg function in net/bluetooth/af bluetooth.c not properly initializing a certain length variable, which can be exploited via a crafted recvmsg or recvfrom system call. Multiple vulnerabilities in the Linux operating system package may lead to disruption of confidentiality, integrity, and availability of protected information, potentially exploitable by a local attacker.

Recommendations For Linux kernel versions prior to 3.9-rc7, update to version 3.9-rc7 or later to resolve the issue. As a temporary workaround, consider restricting access to the bt sock recvmsg function until a patch is available. Avoid using the recvmsg or recvfrom system calls in the affected API endpoints until the issue is resolved.
