The vulnerabilities of the functions tun_get_user() and tun_xdp_one() in the drivers/net/tun.c file of the Linux kernel’s TUN/TAP virtual network interface driver allow a attacker to cause a service failure.
The vulnerability of the tungetuser and tunxdpone functions in the drivers/net/tun.c file of the Linux virtual network interface TUN/TAP driver leads to a lack of memory release after the effective lifespan of these functions has ended. Exploiting this vulnerability can allow an attacker to cause...
