CentOS Errata and Security Advisory CESA-2010:0792

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issue:

  • The rds_page_copy_user() function in the Linux kernel Reliable Datagram
    Sockets (RDS) protocol implementation was missing sanity checks. A local,
    unprivileged user could use this flaw to escalate their privileges.
    (CVE-2010-3904, Important)

Red Hat would like to thank Dan Rosenberg of Virtual Security Research for
reporting this issue.

Users should upgrade to these updated packages, which contain a backported
patch to correct this issue. The system must be rebooted for this update to
take effect.
