  This update fixes the following security issues:

  * Flaws in the AGPGART driver implementation when handling certain IOCTL
  commands could allow a local user to cause a denial of service or escalate
  their privileges. (CVE-2011-1745, CVE-2011-2022, Important)

  * An integer overflow flaw in agp_allocate_memory() could allow a local
  user to cause a denial of service or escalate their privileges.
  (CVE-2011-1746, Important)

  * A race condition flaw was found in the Linux kernel's eCryptfs
  implementation. A local attacker could use the mount.ecryptfs_private
  utility to mount (and then access) a directory they would otherwise not
  have access to. Note: To correct this issue, the RHSA-2011:1241
  ecryptfs-utils update, which provides the user-space part of the fix, must
  also be installed. (CVE-2011-1833, Moderate)

  * A denial of service flaw was found in the way the taskstats subsystem
  handled the registration of process exit handlers. A local, unprivileged
  user could register an unlimited amount of these handlers, leading to
  excessive CPU time and memory use. (CVE-2011-2484, Moderate)

  * A flaw was found in the way mapping expansions were handled. A local,
  unprivileged user could use this flaw to cause a wrapping condition,
  triggering a denial of service. (CVE-2011-2496, Moderate)

  * A flaw was found in the Linux kernel's Performance Events implementation.
  It could falsely lead the NMI (Non-Maskable Interrupt) Watchdog to detect a
  lockup and panic the system. A local, unprivileged user could use this flaw
  to cause a denial of service (kernel panic) using the perf tool.
  (CVE-2011-2521, Moderate)

  * A flaw in skb_gro_header_slow() in the Linux kernel could lead to GRO
  (Generic Receive Offload) fields being left in an inconsistent state. An
  attacker on the local network could use this flaw to trigger a denial of
  service. GRO is enabled by default in all network drivers that support it.
  (CVE-2011-2723, Moderate)

  * A flaw was found in the way the Linux kernel's Performance Events
  implementation handled PERF_COUNT_SW_CPU_CLOCK counter overflow. A local,
  unprivileged user could use this flaw to cause a denial of service.
  (CVE-2011-2918, Moderate)

  * A flaw was found in the Linux kernel's Trusted Platform Module (TPM)
  implementation. A local, unprivileged user could use this flaw to leak
  information to user-space. ( ...
