There is no fixed version for Centos:8 python3-perf.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-perf package and not the python3-perf package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable.
