Since a bit less than a week ago Oracle has released the patchset 18.104.22.168.0 for Oracle 11g Release 2. The current patchset is as well as patchset 22.214.171.124.0 a full installation. This means you will have to download quite a bit from Metalink, altogether 7 files. On My Oracle Support search for patchset 10404530 or follow the link to reach the download page.
So far the patch set is only available for Linux x86 and Linux x86-64bit. The Metalink Note 126.96.36.199 Patch Set – Availability and Known Issues [1348336.1] or the generic ALERT for Oracle 11g Release 2 ALERT: Oracle 11g Release 2 (11.2) Support Status and Alerts [880782.1] will list the patch set for other platforms as soon as they are available.
List of Bugfixes
In the Metalink Note 1348303.1 you find a hell of a long list with bugs fixed in this patchset. I think you would be well advised to test the patchset before installing on production. According to Metalink Note 1348336.1 there are up to now only two notable fixes with potential change in behavior but no new issues introduced in this patchset. But I guess the issues will show up as soon as the Oracle Open World is finished. So check the Metalink Note on updates.
