CVE-2013-3227 describes an information disclosure vulnerability in the Linux kernel, specifically within the caif_seqpkt_recvmsg function in net/caif/caif_socket.c, affecting versions prior to 3.9-rc7. This flaw allows local users to extract sensitive data from kernel stack memory by exploiting an uninitialized length variable through crafted recvmsg or recvfrom system calls. The vulnerability has a CVSS score of 4.9, indicating a medium severity. It requires local access (AV:L) and low attack complexity (AC:L), with no authentication needed (Au:N), leading to a complete confidentiality impact (C:C) but no integrity or availability impact. There is no evidence of active exploitation, and no public exploit code is available on platforms like Metasploit, Nuclei, or ExploitDB. Furthermore, there is minimal community discussion or media coverage surrounding this CVE.
