✅ Remediation

Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. Workaround: For users that do not run applications that use RDS, you can prevent the rds module from being loaded by adding the following entry to the end of the /etc/modprobe.d/blacklist file: blacklist rds This way, the rds module cannot be loaded accidentally, which may occur if an application that requires RDS is started. A reboot is not necessary for this change to take effect but do make sure the module is not loaded in the first place. You can verify that by running: lsmod | grep rds You may also consider removing the CAP_SYS_MODULE capability from the current global capability set to prevent kernel modules from being loaded or unloaded. The CAP_SYS_MODULE has a capability number of 16 (see linux/capability.h). The default value has all the bits set. To remove this capability, you have to clear the 16th bit of the default 32-bit value, e.g. 0xffffff ^ (1 << 16): echo 0xFFFEFFFF > /proc/sys/kernel/cap-bound
