Description

Linux Kernel is prone to an integer overflow vulnerability. An attacker can exploit this issue to cause denial-of-service conditions. Given the nature of this issue, attackers may also be able to execute arbitrary code, but this has not been confirmed. Versions prior to Linux kernel 5.0.11 are vulnerable.

Recommendations

Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn’t needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.

Run all software as a nonprivileged user with minimal access rights.
To limit the potential damage that successful exploits may achieve, run all nonadministrative software as an unprivileged user.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploit attempts or activity that results from successful exploits.

Updates are available. Please see the references or vendor advisory for more information.
