CVE-2013-3227

Published: 22 April 2013

The caif_seqpkt_recvmsg function in net/caif/caif_socket.c in the Linux kernel before 3.9-rc7 does not 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.

From the Ubuntu Security Team

An information leak was discovered in the Linux kernel's CAIF protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory.
