CVE-2025-40144 is fixed in linux on 1 platform, first by DEBIAN-CVE-2025-40144, released November 12, 2025. It is not reported as exploited. Patch Radar priority: Routine.
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.
