DescriptionCVE.org

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.

AnalysisAI

Technical ContextAI

This vulnerability is classified as NULL Pointer Dereference (CWE-476), which allows attackers to crash the application by dereferencing a null pointer. 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.

Affected ProductsAI

See vendor advisory for affected versions.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Check pointers before dereferencing. Use static analysis tools to detect null pointer paths.
