CVE-2025-21663

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: dwmac-tegra: Read iommu stream id from device tree Nvidia's Tegra MGBE controllers require the IOMMU "Stream ID" (SID) to be written to the MGBE_WRAP_AXI_ASID0_CTRL register. The current driver is hard coded to use MGBE0's SID for all controllers. This causes softirq time outs and kernel panics when using controllers other than MGBE0. Example dmesg errors when an ethernet cable is connected to MGBE1: [ 116.133290] tegra-mgbe 6910000.ethernet eth1: Link is Up - 1Gbps/Full - flow control rx/tx [ 121.851283] tegra-mgbe 6910000.ethernet eth1: NETDEV WATCHDOG: CPU: 5: transmit queue 0 timed out 5690 ms [ 121.851782] tegra-mgbe 6910000.ethernet eth1: Reset adapter.

  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: stmmac: dwmac-tegra: Leer el ID de flujo de iommu del árbol de dispositivos Los controladores Tegra MGBE de Nvidia requieren que el "ID de flujo" (SID) de IOMMU se escriba en el registro MGBE_WRAP_AXI_ASID0_CTRL. El controlador actual está codificado de forma rígida para utilizar el SID de MGBE0 para todos los controladores.
