CVE-2023-53568
Linux Kernel vulnerability analysis and mitigation

Overview

In the Linux kernel, a memory leak vulnerability (CVE-2023-53568) was discovered where zcdncreate() fails to free newly allocated resources when devset_name() fails. This vulnerability was reported and disclosed on October 4, 2025 (NVD).

Technical details

The vulnerability exists in the s390/zcrypt subsystem of the Linux kernel. When the devsetname() function fails during device creation, the zcdn_create() function does not properly clean up and free the allocated resources, resulting in a memory leak (NVD).

Impact

The vulnerability could lead to memory resource exhaustion over time as allocated resources are not properly freed when certain error conditions occur in the zcrypt subsystem (NVD).

Mitigation and workarounds

The vulnerability has been fixed in the Linux kernel. System administrators should apply the appropriate kernel updates when they become available through their distribution's security updates (NVD).
