CVE-2026-53120 Details
Description
In the Linux kernel, the following vulnerability has been resolved: PCI: 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 vulnerability in the Linux kernel's PCI driver handling can lead to a use-after-free condition. This issue arises because the bus's match callback is invoked without the device lock, allowing unsynchronized access to the driver_override field. The vulnerability affects the PCI subsystem across various drivers and versions in the Linux kernel stable tree.
Users can update to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for updating the kernel can be found in the official Linux documentation.
