freerdp: FreeRDP: Denial of Service via double free vulnerability during disconnect

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This double free vulnerability occurs during the cleanup process when a remote desktop session disconnects. Specifically, if a title allocation fails, a pointer to an application window is freed but not removed fro...

EUVD-2026-25543

In the Linux kernel, the following vulnerability has been resolved: mmc: vub300: fix use-after-free on disconnect The vub300 driver maintains an explicit reference count for the controller and its driver data and the last reference can in theory be dropped after the driver has been unbound. This...

CVE-2026-31650

The CVE concerns the Linux kernel mmc vub300 driver. The root cause is a use-after-free risk from device-managed controller allocation and a lifetime tie to the parent USB device rather than the interface, which can cause memory leaks if the driver is unbound without a disconnect. A last referenc...
