{"id":"DEBIAN-CVE-2022-49622","details":"In the Linux kernel, the following vulnerability has been resolved:  netfilter: nf_tables: avoid skb access on nf_stolen  When verdict is NF_STOLEN, the skb might have been freed.  When tracing is enabled, this can result in a use-after-free: 1. access to skb-\u003enf_trace 2. access to skb-\u003emark 3. computation of trace id 4. dump of packet payload  To avoid 1, keep a cached copy of skb-\u003enf_trace in the trace state struct. Refresh this copy whenever verdict is != STOLEN.  Avoid 2 by skipping skb-\u003emark access if verdict is STOLEN.  3 is avoided by precomputing the trace id.  Only dump the packet when verdict is not \"STOLEN\".","modified":"2026-09-01T16:04:35.960580399Z","published":"2025-02-26T07:01:37.580Z","upstream":["CVE-2022-49622"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49622"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49622.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49622.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.18.14-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49622.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
