✅ Remediation

Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 Workaround: This issue does not affect most systems by default. An administrator would need to have enabled the BPF JIT to be affected. It can be disabled immediately with the command: # echo 0 > /proc/sys/net/core/bpf_jit_enable Or it can be disabled for all subsequent boots of the system by setting a value in /etc/sysctl.d/44-bpf-jit-disable ## start file ## net.core.bpf_jit_enable=0 ## end file ##
