Description
In the Linux kernel, the following vulnerability has been resolved: clocksource/drivers/cadence-ttc: Fix memory leak in ttc_timer_probe Smatch reports: drivers/clocksource/timer-cadence-ttc.c:529 ttc_timer_probe() warn: 'timer_baseaddr' from of_iomap() not released on lines: 498,508,516. timer_baseaddr may have the problem of not being released after use, I replaced it with the devm_of_iomap() function and added the clk_put() function to cleanup the "clk_ce" and "clk_cs".

Executive Summary

This vulnerability is a memory leak in the Linux kernel's cadence-ttc clocksource driver. Specifically, the 'timer_baseaddr' obtained from the of_iomap() function was not properly released after use in the ttc_timer_probe() function, leading to a resource leak. The fix involved replacing of_iomap() with devm_of_iomap() and adding cleanup calls to release associated clock resources.

Impact Analysis

The memory leak caused by this vulnerability can lead to inefficient use of system memory and resources, potentially degrading system performance or stability over time if the driver is repeatedly probed or used. However, it does not directly lead to security breaches like data exposure or privilege escalation.
