Description
In the Linux kernel, the following vulnerability has been resolved: tty: serial: ip22zilog: Use platform device for probing After commit 84a9582fd203 ("serial: core: Start managing serial controllers to enable runtime PM") serial drivers need to provide a device in struct uart_port.dev otherwise an oops happens. To fix this issue for ip22zilog driver switch driver to a platform driver and setup the serial device in sgi-ip22 code.

Executive Summary

This vulnerability relates to the Linux kernel's serial driver for ip22zilog. After a change to start managing serial controllers for runtime power management, serial drivers must provide a device in the uart_port.dev structure. The ip22zilog driver did not do this, causing a kernel oops (crash). The fix involved switching the driver to a platform driver and properly setting up the serial device in the sgi-ip22 code.

Impact Analysis

This vulnerability can cause the Linux kernel to crash (oops) when using the ip22zilog serial driver, potentially leading to system instability or downtime on affected systems.
