SUSE CVE-2026-31658

In the Linux kernel, the following vulnerability has been resolved: net: altera-tse: fix skb leak on DMA mapping error in tsestartxmit When dmamapsingle fails in tsestartxmit, the function returns NETDEVTXOK without freeing the skb. Since NETDEVTXOK tells the stack the packet was consumed, the sk...

Linux Distros Unpatched Vulnerability : CVE-2026-31658

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: altera-tse: fix skb leak on DMA mapping error in tsestartxmit When dmamapsingle fails in tsestartxmit, the function returns NETDEVTXOK without freeing the...

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...

CVE-2026-31658

CVE-2026-31658 affects the Linux kernel net: altera-tse driver. The root cause is a memory leak: when dma_map_single() fails in tse_start_xmit(), the code returns NETDEV_TX_OK without freeing the skb, causing the skb to be leaked on every DMA mapping failure. The provided patches add dev_kfree_sk...
