CVE-2026-53120

UnknownEPSS 0.16%

Last modified

CVE-2026-53120 is a vulnerability of currently unknown severity. 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]. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
