CVE-2018-10124

Published: 16 April 2018

The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.

From the Ubuntu Security Team

It was discovered that the kill() system call implementation in the Linux kernel did not properly validate its arguments in some situations. A local attacker could possibly use this to cause a denial of service.
