CVE-2011-2482
Published: 8 June 2013
A certain Red Hat patch to the sctp_sock_migrate function in net/sctp/socket.c in the Linux kernel before 2.6.21, as used in Red Hat Enterprise Linux (RHEL) 5, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) via a crafted SCTP packet.

|---|---|
| apw | this bug was introduced by a flawed backport of commit ea2bc483ff5caada7c4aa0d5fbf87d3a6590273d to the RHEL kernel, this was mainlined in v2.6.21 and therefore no existing release has this backported |
