CVE-2023-53308 net: fec: Better handle pm_runtime_get() failing in .remove()

What is CVE-2023-53308?

CVE-2023-53308 is a high-severity vulnerability in Linux kernel, published on 16 Sep 2025. It can only be exploited from the same machine or local network, with no action from the victim.

Official 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.

Weakness: CWE-415
