CVE-2026-53119 Details
Description
In the Linux kernel, the following vulnerability has been resolved: platform/wmi: use generic driver_override infrastructure When a driver is probed through __driver_attach(), the bus' match() callback is called without the device lock held, thus accessing the driver_override field without a lock, which can cause a UAF. Fix this by using the driver-core driver_override infrastructure taking care of proper locking internally. Note that calling match() from __driver_attach() without the device lock held is intentional. [1]
A use-after-free vulnerability has been identified in the Linux kernel's WMI (Windows Management Instrumentation) platform driver. This issue arises because the driver's match() callback is invoked without holding the device lock, allowing unsynchronized access to the driver_override field. Such access can lead to a use-after-free condition. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the official Linux kernel website.
