{"id":"ALPINE-CVE-2020-29568","details":"An issue was discovered in Xen through 4.14.x. Some OSes (such as Linux, FreeBSD, and NetBSD) are processing watch events using a single thread. If the events are received faster than the thread is able to handle, they will get queued. As the queue is unbounded, a guest may be able to trigger an OOM in the backend. All systems with a FreeBSD, Linux, or NetBSD (any version) dom0 are vulnerable.","modified":"2026-09-14T13:30:02.467927224Z","published":"2020-12-15T17:15:14.660Z","upstream":["CVE-2020-29568"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-29568"}],"affected":[{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}},{"package":{"name":"linux-lts","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/linux-lts?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.10.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2020-29568.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H"}]}
