AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue is related to the functions crst table free() and base crst free() in the Linux kernel's memory management subsystem on the s390 platform. The problem arises from the potential dereference of a null pointer. In real-life scenarios, this should not occur because order two GFP KERNEL allocations will not fail unless FAIL PAGE ALLOC is enabled and used. The vulnerability could allow an attacker to cause a denial of service.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
