Description
In the Linux kernel, the following vulnerability has been resolved: net: fec: Better handle pm_runtime_get() failing in .remove() In the (unlikely) event that pm_runtime_get() (disguised as pm_runtime_resume_and_get()) fails, the remove callback returned an error early. The problem with this is that the driver core ignores the error value and continues removing the device. This results in a resource leak. Worse the devm allocated resources are freed and so if a callback of the driver is called later the register mapping is already gone which probably results in a crash.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability occurs in the Linux kernel's fec driver where, if the function pm_runtime_get() (called as pm_runtime_resume_and_get()) fails during device removal, the remove callback returns an error early. However, the driver core ignores this error and continues removing the device, leading to a resource leak. Additionally, resources allocated with devm are freed prematurely, so if a driver callback is called later, it may access freed memory causing a crash.


How can this vulnerability impact me? :

The vulnerability can cause resource leaks and potentially lead to system crashes due to use-after-free conditions when driver callbacks access freed resources. This can affect system stability and reliability.
