CVE-2026-53117

A flaw was found in the Linux kernel, specifically within the s390/cio component. When a driver is being probed, a race condition can occur where the driveroverride field is accessed without proper locking. This can lead to a Use-After-Free UAF vulnerability, which may result in system instabilit...

Linux Distros Unpatched Vulnerability : CVE-2026-53117

EUVD-2026-38985

In the Linux kernel, the following vulnerability has been resolved: s390/cio: use generic driveroverride infrastructure When a driver is probed through driverattach, the bus' match callback is called without the device lock held, thus accessing the driveroverride field without a lock, which can...

CVE-2026-53117

The CVE-2026-53117 issue affects the Linux kernel (s390/cio). During driver probing in __driver_attach(), the bus match() callback can access the driver_override field without the required device lock, creating a potential use-after-free. The fix switches to the driver-core driver_override infras...
