CVE-2022-4744

CVE-2022-4744 describes a local, double-free flaw in the Linux kernel’s TUN/TAP device driver during register_netdevice failure, potentially crashing the host or enabling privilege escalation. Connected Astra Linux bulletin corroborates a Linux-5.10 kernel context with the same double-free issue ...

CVE-2023-1076

A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While it will be often correct, as tuntap devices require CAPNETADMIN, it may not always be the case, e.g., a non-root user only having that...

CVE-2023-1076

CVE-2023-1076 describes a Linux kernel flaw in tun/tap initialisation where the socket uid is hardcoded to 0 due to a type confusion. The result can cause tun/tap sockets to be treated as if they have root privileges when filtering/routing decisions are made, potentially bypassing network filters...
