CVE-2022-49642

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: stmmac: dwc-qos: Disable split header for Tegra194<br /> <br /> There is a long-standing issue with the Synopsys DWC Ethernet driver<br /> for Tegra194 where random system crashes have been observed [0]. The<br /> problem occurs when the split header feature is enabled in the stmmac<br /> driver. In the bad case, a larger than expected buffer length is<br /> received and causes the calculation of the total buffer length to<br /> overflow. This results in a very large buffer length that causes the<br /> kernel to crash. Why this larger buffer length is received is not clear,<br /> however, the feedback from the NVIDIA design team is that the split<br /> header feature is not supported for Tegra194. Therefore, disable split<br /> header support for Tegra194 to prevent these random crashes from<br /> occurring.<br /> <br /> [0] https://lore.kernel.org/linux-tegra/b0b17697-f23e-8fa5-3757-604a86f3a095@nvidia.com/
