This scheme is used to maintain invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately, the logic for acquiring a type reference has a race condition, whereby a safely TLB flush is issued too early and creates a window where the guest can re-establish the read/write mapping before writeability is prohibited.","severity":{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","level":"medium","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-09","score":0.00385,"percentile":0.32843,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-362"],"published":"2022-06-09T12:50:19Z","modified":"2026-11-03T08:01:06Z","fixes":[{"ecosystem":"Alpine:v3.13","package":"xen","fixed_in":["4.14.5-r1"],"sources":["osv"]},{"ecosystem":"Alpine:v3.14","package":"xen","fixed_in":["4.15.2-r1"],"sources":["osv"]},{"ecosystem":"Alpine:v3.15","package":"xen","fixed_in":["4.15.2-r1"],"sources":["osv"]},{"ecosystem":"Alpine:v3.16","package":"xen","fixed_in":["4.16.1-r1"],"sources":["osv"]},{"ecosystem":"Alpine:v3.17","package":"xen","fixed_in":["4.16.1-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.18","package":"xen","fixed_in":["4.16.1-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"xen","fixed_in":["4.16.1-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"xen","fixed_in":["4.16.1-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.21","package":"xen","fixed_in":["4.16.1-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"xen","fixed_in":["4.16.1-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"xen","fixed_in":["4.16.1-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"xen","fixed_in":["4.16.1-r2"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"xen","fixed_in":["4.16.2-1"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"xen","fixed_in":["4.16.2-1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"xen","fixed_in":["4.16.2-1"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpine:v3.13","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.14.5-r1"}]}]},{"source":"osv","ecosystem":"Alpine:v3.14","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.15.2-r1"}]}]},{"source":"osv","ecosystem":"Alpine:v3.15","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.15.2-r1"}]}]},{"source":"osv","ecosystem":"Alpine:v3.16","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r1"}]}]},{"source":"osv","ecosystem":"Alpine:v3.17","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.18","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.19","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.20","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.21","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.22","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.23","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.24","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r2"}]}]},{"source":"osv","ecosystem":"Debian:12","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.2-1"}]}]},{"source":"osv","ecosystem":"Debian:13","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.2-1"}]}]},{"source":"osv","ecosystem":"Debian:14","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.2-1"}]}]},{"source":"osv","ecosystem":"Debian:11","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.14.5+24-g87d90d511c-1"}]}],"versions":["4.14.2+25-gb6a8c4f72d-2","4.14.3+32-g9de3671772-1","4.14.3+32-g9de3671772-1~deb11u1","4.14.3-1","4.14.3-1~deb11u1","4.14.4+74-gd7b22226b5-1"],"bundled":8},{"source":"osv","ecosystem":"SUSE:Linux
