{"id":"DEBIAN-CVE-2024-24856","details":"The memory allocation function ACPI_ALLOCATE_ZEROED does not guarantee a successful allocation, but the subsequent code directly dereferences the pointer that receives it, which may lead to null pointer dereference.  To fix this issue, a null pointer check should be added. If it is null,  return exception code AE_NO_MEMORY.","modified":"2026-09-15T09:02:59.470027393Z","published":"2024-04-17T09:15:07.743Z","upstream":["CVE-2024-24856"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-24856"}],"affected":[{"package":{"name":"acpica-unix","ecosystem":"Debian:12","purl":"pkg:deb/debian/acpica-unix?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20200925-8","20230331-2","20230628-1","20240322-1","20240322-2","20240827-2","20240927-1","20241212-2","20250404-1","20250807-1","20251212-1","20260408-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-24856.json"}},{"package":{"name":"acpica-unix","ecosystem":"Debian:13","purl":"pkg:deb/debian/acpica-unix?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"20240827-2"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-24856.json"}},{"package":{"name":"acpica-unix","ecosystem":"Debian:14","purl":"pkg:deb/debian/acpica-unix?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"20240827-2"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-24856.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:N/I:N/A:H"}]}
