A vulnerability in the Linux kernel's tun driver was resolved, where a failure in the build_skb() function within tun_xdp_one() could cause a memory leak by not freeing allocated pages. This issue could lead to resource exhaustion. The vulnerability affects multiple versions of the linux-hwe-edge kernel prior to specific fixed versions. A patch is available and should be applied to prevent the memory leak.

The Linux kernel tun driver had a flaw in tun_xdp_one() where if build_skb() failed, the allocated page was not freed, causing a memory leak. Specifically, when build_skb() returns an error, the function returns without freeing the page allocated by vhost_net_build_xdp(), and tun_sendmsg() incorrectly treats the operation as successful, leading to unreleased memory pages accumulating. This vulnerability has been fixed in updated kernel versions.
