{"id":"DEBIAN-CVE-2023-52940","details":"In the Linux kernel, the following vulnerability has been resolved:  mm: multi-gen LRU: fix crash during cgroup migration  lru_gen_migrate_mm() assumes lru_gen_add_mm() runs prior to itself.  This isn't true for the following scenario:      CPU 1                         CPU 2    clone()     cgroup_can_fork()                                 cgroup_procs_write()     cgroup_post_fork()                                   task_lock()                                   lru_gen_migrate_mm()                                   task_unlock()     task_lock()     lru_gen_add_mm()     task_unlock()  And when the above happens, kernel crashes because of linked list corruption (mm_struct-\u003elru_gen.list).","modified":"2026-09-15T09:02:49.313037838Z","published":"2025-03-27T17:15:43.920Z","upstream":["CVE-2023-52940"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-52940"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-52940.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-52940.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.11-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-52940.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:N/I:N/A:H"}]}
