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."}],"affected":[{"vendor":"n/a","product":"Linux kernel","versions":[{"version":"unknown","status":"affected"}]}],"references":[{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=66b2c338adce580dfce2199591e65e2bab889cff"},{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=a096ccca6e503a5c575717ff8a36ace27510ab0a"},{"name":"[debian-lts-announce] 20230502 [SECURITY] [DLA 3404-1] linux-5.10 security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html"}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-791","cweId":"CWE-791"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T05:32:46.361Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=66b2c338adce580dfce2199591e65e2bab889cff","tags":["x_transferred"]},{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=a096ccca6e503a5c575717ff8a36ace27510ab0a","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20230502 [SECURITY] [DLA 3404-1] linux-5.10 security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html"}]},{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.5,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2025-02-24T17:04:00.621102Z","id":"CVE-2023-1076","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-02-24T17:04:30.565Z"}}]}}
