CVE-2022-50151: Linux kernel CDNS3 driver may log spurious warning
CVE-2022-50151 · published 1 year ago
Summary
The CDNS3 USB driver in the Linux kernel could produce an unexpected warning message during startup, caused by an unnecessary memory flag. While the warning does not affect system operation, it can clutter logs and make troubleshooting harder. Updating the kernel to the latest version removes the flag and eliminates the harmless warning.
