CVE-2026-97963

A flaw was found in the Linux kernel's stmmac network driver. An uninitialized read-write lock is accessed when configuring traffic control scheduling on an interface that has not been brought up. A local user with network administration privileges could exploit this flaw to cause a kernel crash,...

CVE-2026-97953

A flaw was found in the Linux kernel's stmmac network driver. An attacker can cause a Denial of Service DoS by transmitting highly fragmented network packets that use TCP Segmentation Offload TSO. Due to an improper calculation of required transmit descriptors, the driver writes past available...

CVE-2026-93830

A flaw was found in the Linux kernel's stmmac network driver. An attacker can cause a Denial of Service DoS by sending high volumes of network traffic to an affected system. Under heavy packet load, the network controller exhausts its receive buffers and continuously fires hardware interrupts...

ROS-20260929-73-0058

The vulnerability of the jumbofrm function in the drivers/net/ethernet/stmicro/stmmac/chainmode.c file of the Ethernet network adapter driver for the Linux operating system is related to a numerical overflow issue. Exploiting this vulnerability could allow an attacker to compromise the...

ROS-20260929-73-0175

The vulnerability of the stmmac/stmmacmain.c component in the Linux operating system is related to pointer dereferencing errors. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-98131

A flaw was found in the Linux kernel's stmmac network driver. During network packet transmission, a failure in Direct Memory Access DMA mapping for packet fragments causes the driver to drop the packet without releasing previously allocated mappings. A local user could exploit this flaw by...

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...
