CVE-2026-31695
CVE-2026-31695 is a Linux kernel issue affecting the virt_wifi driver. The root cause is a race during unregistration where a device’s parent pointer could reference freed memory, causing a use-after-free during ethtool operations. The vulnerability arises from using SET_NETDEV_DEV(dev, &priv->...
CVE-2026-31576
A flaw was found in the Linux kernel's hackrf driver. A race condition exists where memory for the hackrf device is freed prematurely during device unregistration, even when file descriptors are still in use. This allows a local user to trigger a use-after-free and double-free vulnerability...
