  "cwe" : "CWE-772",
  "details" : [ "A flaw was found in the Linux kernel's net: altera-tse network driver. When a Direct Memory Access (DMA) mapping error occurs in the tse_start_xmit() function, the system fails to free the allocated socket buffer (skb). This oversight causes a memory leak with each DMA mapping failure, potentially leading to resource exhaustion and a Denial of Service (DoS) condition." ],
