Yesterday Update ROllup 5 for System Center 2012 was released.
It contains fixes for VMM 2012 and SCOM 2012. Keep in mind that this does not include the 2012 SP1, who have their own set of update rollups. From the KB site:
Issues that are fixed in Update Rollup 5
Virtual Machine Manager (KB2824618)
Issue 1
A host that is put into maintenance mode does not load-balance virtual machines in a cluster during evacuation. This causes host reserve saturation.
Operations Manager (KB2831729)
Issue 1
The Solaris agent could run out of file descriptors when many multi-version file systems (MVFS) are mounted.
Issue 2
Logical and physical disks are not discoverable on AIX-based computers when a disk device file is contained in a subdirectory.
Issue 3
Rules and monitors that were created by using the UNIX/Linux Shell Command templates do not contain overridable ShellCommand and Timeout parameters.
Issue 4
Process monitors that were created by using the UNIX/Linux Process Monitoring template cannot save in an existing management pack that has conflicting references to library management packs.
Issue 5
The Linux agent cannot install on a CentOS or Oracle Linux host by using the FIPS version of OpenSSL 0.9.8.
