CyberRota Analysis

AI-Generated

The vulnerability affects the Linux kernel, specifically during the early boot process when an invalid or empty baud rate is provided for the console=uart8250 parameter. This can lead to a division by zero error in the early_serial_init() function, causing the system to hang. Organizations using Linux systems, particularly those relying on serial console configurations, should prioritize addressing this issue to ensure reliable boot processes.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: x86/boot: Validate console=uart8250 baud rate to fix early boot hang When the baud rate is empty, 0, invalid, or overflows to 0 when stored as an int, the system will hang during early boot because of a division by zero in early_serial_init(). Fall back to DEFAULT_BAUD when the resulting baud rate is 0 to prevent an early system hang.
