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 CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing network filters.\n\ud83d\udccf Published: 2023-03-27T00:00:00.000Z\n\ud83d\udccf Modified: 2025-02-24T17:04:30.565Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=66b2c338adce580dfce2199591e65e2bab889cff\n2. https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=a096ccca6e503a5c575717ff8a36ace27510ab0a\n3. https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html", "creation_timestamp": "2025-02-24T17:21:43.000000Z"}
