CVE-2026-31658

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 tsestartxmit function, the system fails to free the allocated socket buffer skb. This oversight causes a memory leak with each DMA mapping failure, potentially leadin...
