A flaw was found in the Linux kernel's nvme-tcp component. When block devices are created in parallel threads, the page_frag_cache is used in a manner that is not thread-safe. This can lead to incorrect reference counting of memory pages and premature freeing, potentially causing a system crash (Denial of Service).
