CVE-2017-18261

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.13

Description: The issue allows local users to cause a denial of service, specifically infinite recursion, under certain circumstances. This can be achieved by writing to a file under /sys/kernel/debug, and a scenario involving debugfs, ftrace, PREEMPT TRACER, and FUNCTION GRAPH TRACER has been demonstrated.

Recommendations: For versions prior to 4.13, update to version 4.13 or later to resolve the issue. As a temporary workaround, consider restricting access to the /sys/kernel/debug directory to minimize the risk of exploitation.
