CVE-2026-98131

The Linux kernel contains a DMA mapping leak within the stmmac_tso_xmit() function. When a DMA mapping for an skb fragment fails, the system drops the frame but fails to unmap the DMA mappings already established for the linear part and preceding fragments. This flaw leads to a persistent leak of...

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix TX descriptor availability check for TSO traffic stmmactsoxmit estimates the number of free TX descriptors required by a TSO skb as: skb-len - protohdrlen / TSOMAXBUFFSIZE + 1 which assumes the payload is split...

The vulnerability of the stmmac_tso_xmit() function in the drivers/net/ethernet/stmicro/stmmac/stmmac_main.c file of the Ethernet adapter support driver from STMicroelectronics’ operating system Linux allows a hacker to cause a service failure.

The vulnerability of the stmmactsoxmit function in the drivers/net/ethernet/stmicro/stmmac/stmmacmain.c file of the Ethernet driver module from STMicroelectronics’ operating system Linux is related to the lack of proper validation for incoming requests. Exploiting this vulnerability could allow a...
