There is no fixed version for Centos:7 kernel-rt-debug.

See How to fix? for Centos:7 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
powerpc/lib: Validate size for vector operations
Some of the fp/vmx code in sstep.c assume a certain maximum size for the instructions being emulated. The size of those operations however is determined separately in analyse_instr().
Add a check to validate the assumption on the maximum size of the operations, so as to prevent any unintended kernel stack corruption.
