CVE-2008-4113 Information

Description

The sctp_getsockopt_hmac_ident function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.26.4 when the SCTP-AUTH extension is enabled relies on an untrusted length value to limit copying of data from kernel memory which allows local users to obtain sensitive information via a crafted SCTP_HMAC_IDENT IOCTL request involving the sctp_getsockopt function.
