CVE-2019-20934

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.2.6

Description The issue is related to a use-after-free in the show numa stats() function of the Linux kernel's NUMA system, caused by the inappropriate freeing of NUMA fault statistics. This can potentially allow an attacker to cause a denial of service.

Recommendations For Linux kernel versions prior to 5.2.6, update to version 5.2.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the show numa stats() function to minimize the risk of exploitation.
