A flaw was found in the Linux kernel’s implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.
Possible mitigation would be to disable core dumps system-wide by setting:
In the /etc/security/limits.conf file and restarting applications/services/processes which users may have access to or simply reboot the system. This disables core dumps which may not be a suitable workaround in your environment.
