{"id":"DEBIAN-CVE-2024-53113","details":"In the Linux kernel, the following vulnerability has been resolved:  mm: fix NULL pointer dereference in alloc_pages_bulk_noprof  We triggered a NULL pointer dereference for ac.preferred_zoneref-\u003ezone in alloc_pages_bulk_noprof() when the task is migrated between cpusets.  When cpuset is enabled, in prepare_alloc_pages(), ac-\u003enodemask may be &current-\u003emems_allowed.  when first_zones_zonelist() is called to find preferred_zoneref, the ac-\u003enodemask may be modified concurrently if the task is migrated between different cpusets.  Assuming we have 2 NUMA Node, when traversing Node1 in ac-\u003ezonelist, the nodemask is 2, and when traversing Node2 in ac-\u003ezonelist, the nodemask is 1.  As a result, the ac-\u003epreferred_zoneref points to NULL zone.  In alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() finds a allowable zone and calls zonelist_node_idx(ac.preferred_zoneref), leading to NULL pointer dereference.  __alloc_pages_noprof() fixes this issue by checking NULL pointer in commit ea57485af8f4 (\"mm, page_alloc: fix check for NULL preferred_zone\") and commit df76cee6bbeb (\"mm, page_alloc: remove redundant checks from alloc fastpath\").  To fix it, check NULL pointer for preferred_zoneref-\u003ezone.","modified":"2026-09-15T09:03:16.022914190Z","published":"2024-12-02T14:15:12.097Z","upstream":["CVE-2024-53113"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-53113"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.119-1"}]}],"versions":["6.1.106-1","6.1.106-2","6.1.106-3","6.1.112-1","6.1.115-1","6.1.27-1","6.1.37-1","6.1.38-1","6.1.38-2","6.1.38-2~bpo11+1","6.1.38-3","6.1.38-4","6.1.38-4~bpo11+1","6.1.52-1","6.1.55-1","6.1.55-1~bpo11+1","6.1.64-1","6.1.66-1","6.1.67-1","6.1.69-1","6.1.69-1~bpo11+1","6.1.76-1","6.1.76-1~bpo11+1","6.1.82-1","6.1.85-1","6.1.90-1","6.1.90-1~bpo11+1","6.1.94-1","6.1.94-1~bpo11+1","6.1.98-1","6.1.99-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-53113.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.11.10-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-53113.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.11.10-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-53113.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"}]}
