EUVD-2025-203757

In the Linux kernel, the following vulnerability has been resolved: usbnet: Prevents free active kevent The root cause of this issue are: 1. When probing the usbnet device, executing usbnetlinkchangedev, 0, 0; put the kevent work in global workqueue. However, the kevent has not yet been scheduled...

EUVD-2025-203773

In the Linux kernel, the following vulnerability has been resolved: can: gsusb: gsusbxmitcallback: fix handling of failed transmitted URBs The driver lacks the cleanup of failed transfers of URBs. This reduces the number of available URBs per error by 1. This leads to reduced performance and...

CVE-2025-68312

CVE-2025-68312 affects the Linux kernel usbnet subsystem. Root cause: during usbnet probing, usbnet_link_change(dev,0,0) queues a kevent on the global workqueue, which may still be active when the device is unregistered, causing a potential free of an active kevent object. The added fix cancels t...

CVE-2025-68191 udp_tunnel: use netdev_warn() instead of netdev_WARN()

In the Linux kernel, the following vulnerability has been resolved: udptunnel: use netdevwarn instead of netdevWARN netdevWARN uses WARN/WARNON to print a backtrace along with file and line information. In this case, udptunnelnicregister returning an error is just a failed operation, not a kernel...

CVE-2025-68191

In the Linux kernel, CVE-2025-68191 is addressed by replacing netdev_WARN() with netdev_warn() in udp_tunnel_nic_register(). The old netdev_WARN() prints a backtrace via WARN/WARN_ON, which is inappropriate for an error that is simply a normal memory-allocation failure (kzalloc() or udp_tunnel_ni...
