In the Linux kernel, the following vulnerability has been resolved:
nvdimm: ndtest: Return -ENOMEM if devm_kcalloc() fails in ndtest_probe()
devm_kcalloc() may fail. ndtest_probe() allocates three DMA address
arrays (dcr_dma, label_dma, dimm_dma) and later unconditionally uses
them in ndtest_nvdimm_init(), which can lead to a NULL pointer
dereference under low-memory conditions.
Check all three allocations and return -ENOMEM if any allocation fails,
jumping to the common error path. Do not emit an extra error message
since the allocator already warns on allocation failure.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-40144? CVE-2025-40144 is a unknown-severity security vulnerability. No fixed version is listed yet.
- Is there a fix for CVE-2025-40144? No fixed version is listed for CVE-2025-40144 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2025-40144 exploitable, and should I be worried? Whether CVE-2025-40144 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-40144 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
