This will allow two malicious guests working together to create an arbitrary number of Xenstore nodes. This is possible by domain A letting domain B write into domain A's local Xenstore tree. Domain B can then create many nodes and reboot. The nodes created by domain B will now be owned by Dom0. By repeating this process over and over again an arbitrary number of nodes can be created, as Dom0's number of nodes isn't limited by Xenstore quota.","severity":{"version":"3.1","score":5.5,"vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","level":"medium","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-10","score":0.00306,"percentile":0.23588,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-401"],"published":"2022-11-01T00:00:00Z","modified":"2026-11-03T08:03:55Z","fixes":[{"ecosystem":"Alpine:v3.14","package":"xen","fixed_in":["4.15.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.15","package":"xen","fixed_in":["4.15.4-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.16","package":"xen","fixed_in":["4.16.3-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.17","package":"xen","fixed_in":["4.16.3-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.18","package":"xen","fixed_in":["4.17.0-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"xen","fixed_in":["4.17.0-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"xen","fixed_in":["4.17.0-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.21","package":"xen","fixed_in":["4.17.0-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"xen","fixed_in":["4.17.0-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"xen","fixed_in":["4.17.0-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"xen","fixed_in":["4.17.0-r0"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"xen","fixed_in":["4.16.2+90-g0d39a6d1ae-1"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"xen","fixed_in":["4.16.2+90-g0d39a6d1ae-1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"xen","fixed_in":["4.16.2+90-g0d39a6d1ae-1"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpine:v3.14","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.15.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.15","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.15.4-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.16","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.3-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.17","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.3-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.18","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.0-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.19","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.0-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.20","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.0-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.21","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.0-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.22","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.0-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.23","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.0-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.24","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.17.0-r0"}]}]},{"source":"osv","ecosystem":"Debian:12","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.2+90-g0d39a6d1ae-1"}]}]},{"source":"osv","ecosystem":"Debian:13","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.2+90-g0d39a6d1ae-1"}]}]},{"source":"osv","ecosystem":"Debian:14","package":"xen","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.16.2+90-g0d39a6d1ae-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
