To address XSA-401, code was moved inside a function in Xen. This code movement missed a variable changing meaning / value between old and new code positions. The now wrong use of the variable did lead to a wrong TLB flush condition, omitting flushes where such are necessary.","severity":{"version":"3.1","score":8.8,"vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","level":"high","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-08","score":0.00299,"percentile":0.22717,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"published":"2022-07-26T00:00:00Z","modified":"2026-11-03T08:03:00Z","fixes":[{"ecosystem":"Alpine:v3.13","package":"xen","fixed_in":["4.14.5-r5"],"sources":["osv"]},{"ecosystem":"Alpine:v3.14","package":"xen","fixed_in":["4.15.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.15","package":"xen","fixed_in":["4.15.3-r2"],"sources":["osv"]},{"ecosystem":"Alpine:v3.17","package":"xen","fixed_in":["4.16.1-r6"],"sources":["osv"]},{"ecosystem":"Alpine:v3.18","package":"xen","fixed_in":["4.16.1-r6"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"xen","fixed_in":["4.16.1-r6"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"xen","fixed_in":["4.16.1-r6"],"sources":["osv"]},{"ecosystem":"Alpine:v3.21","package":"xen","fixed_in":["4.16.1-r6"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"xen","fixed_in":["4.16.1-r6"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"xen","fixed_in":["4.16.1-r6"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"xen","fixed_in":["4.16.1-r6"],"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-r5"}]}]},{"source":"osv","ecosystem":"Alpine:v3.14","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.15.3-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.15","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.15.3-r2"}]}]},{"source":"osv","ecosystem":"Alpine:v3.17","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r6"}]}]},{"source":"osv","ecosystem":"Alpine:v3.18","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r6"}]}]},{"source":"osv","ecosystem":"Alpine:v3.19","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r6"}]}]},{"source":"osv","ecosystem":"Alpine:v3.20","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r6"}]}]},{"source":"osv","ecosystem":"Alpine:v3.21","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r6"}]}]},{"source":"osv","ecosystem":"Alpine:v3.22","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r6"}]}]},{"source":"osv","ecosystem":"Alpine:v3.23","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r6"}]}]},{"source":"osv","ecosystem":"Alpine:v3.24","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.1-r6"}]}]},{"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+86-g1c354767d5-1"}]}],"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","4.14.5+24-g87d90d511c-1"],"bundled":22},{"source":"osv","ecosystem":"SUSE:Linux
