{"id":"DEBIAN-CVE-2026-119053","details":"lwIP 2.0.0 through 2.2.1 built with the SNMP agent contains an out-of-bounds read vulnerability in snmp_pbuf_stream_writeto() that bounds copies by pbuf-\u003elen instead of remaining bytes. Remote unauthenticated attackers knowing the read community can send fragmented SNMP requests to receive adjacent receive-buffer or pool memory echoed in responses.","modified":"2026-10-30T07:00:06.783067880Z","published":"2026-10-29T14:17:52.463Z","upstream":["CVE-2026-119053"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-119053"}],"affected":[{"package":{"name":"lwip","ecosystem":"Debian:12","purl":"pkg:deb/debian/lwip?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.3+dfsg1-2","2.1.3+dfsg1-3","2.1.3+dfsg1-4","2.2.0+dfsg1-1","2.2.0+dfsg1-2","2.2.0+dfsg1-3","2.2.0+dfsg1-4","2.2.0+dfsg1-5","2.2.0+dfsg1-6","2.2.0+dfsg1-6.1","2.2.0+dfsg1-6.1~exp1","2.2.0+dfsg1-7","2.2.0+dfsg1-8","2.2.0+dfsg1-9","2.2.1+dfsg1-1","2.2.1+dfsg1-2","2.2.1+dfsg1-3","2.2.1+dfsg1-4","2.2.1+dfsg1-5","2.2.1+dfsg1-6","2.2.1+dfsg1-7","2.2.1+dfsg1-8","2.2.1+dfsg1-9"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-119053.json"}},{"package":{"name":"lwip","ecosystem":"Debian:13","purl":"pkg:deb/debian/lwip?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1+dfsg1-1","2.2.1+dfsg1-1+deb13u1","2.2.1+dfsg1-2","2.2.1+dfsg1-3","2.2.1+dfsg1-4","2.2.1+dfsg1-5","2.2.1+dfsg1-6","2.2.1+dfsg1-7","2.2.1+dfsg1-8","2.2.1+dfsg1-9"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-119053.json"}},{"package":{"name":"lwip","ecosystem":"Debian:14","purl":"pkg:deb/debian/lwip?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1+dfsg1-1","2.2.1+dfsg1-2","2.2.1+dfsg1-3","2.2.1+dfsg1-4","2.2.1+dfsg1-5","2.2.1+dfsg1-6","2.2.1+dfsg1-7","2.2.1+dfsg1-8","2.2.1+dfsg1-9"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-119053.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
