Type/Severity
Product Enhancement Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated microcode_ctl package that fixes a bug and adds various enhancements
is now available for Red Hat Enterprise Linux 6.
Description
The microcode_ctl package provides microcode updates for Intel and AMD
processors.
This updated package fixes the following bug:
- A previous update introduced a memory leak when loading the updated microcode
into memory prior to conversion of said microcode into a format suitable for the
CPU. This update includes a corrected patch that de-allocates the memory
correctly, ensuring memory does not leak. (BZ#684009)
In addition, this updated package provides the following enhancements:
- The Intel CPU microcode file has been updated to version 20110915, which is
the most recent version of the microcode available from Intel. (BZ#696582)
- The AMD CPU microcode file version 20110111 is now included in the package.
(BZ#682668)
Note that the system must be rebooted in order for these changes to take effect.
Users are advised to upgrade to this updated microcode_ctl package, which fixes
this bug and adds these enhancements.
Solution
Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.
