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.
