CVE-2024-24856 (opens in a new tab)How to fix?
Upgrade Debian:14 acpica-unix to version 20240827-2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream acpica-unix package and not the acpica-unix package as distributed by Debian.
See How to fix? for Debian:14 relevant fixed versions and status.
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.
