Description
A flaw was found in the Linux kernel's Non-Volatile Memory Express (NVMe) target subsystem. When handling peer-to-peer (P2P) memory requests, an allocation failure during metadata processing causes the cleanup handler to reference an unassigned device structure. An attacker could exploit this flaw to cause a kernel crash, resulting in a Denial of Service (DoS).
