FKIE_CVE-2024-24856

Vulnerability from fkie_nvd - Published: 2024-04-17 09:15 - Updated: 2024-11-21 08:59
Severity ?
5.3 (Medium) - CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:N/I:N/A:H
Summary
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.
