Vulnerability Title
net: stmmac: dwmac-tegra: Read iommu stream id from device tree
来源: CVE Program / CVE List V5
Vulnerability Description
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:
