FKIE_CVE-2026-53120
Vulnerability from fkie_nvd - Published: 2026-06-24 17:17 - Updated: 2026-06-24 17:17
Severity
Summary
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]
