发布于3月6日3月6日 Members Debian: CVE-2023-1076: linux -- security update Severity 5 CVSS (AV:L/AC:L/Au:S/C:N/I:C/A:N) Published 03/27/2023 Created 05/05/2023 Added 05/01/2023 Modified 01/28/2025 Description 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 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.
