Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in the arm-smmu-v3.c file. It occurs due to a logic error in multiple functions, allowing an attacker to exploit it for local privilege escalation. Exploitation requires system execution privileges but no user interaction.

Impact Analysis

An attacker could exploit this to gain higher privileges on your system, potentially allowing them to execute arbitrary code or take control of your device. This could lead to unauthorized access or data manipulation.

Compliance Impact

This vulnerability involves a use-after-free issue in arm-smmu-v3.c that could lead to local privilege escalation. While it requires system execution privileges, it may impact compliance by potentially allowing unauthorized access or data manipulation, which could violate confidentiality and integrity requirements in standards like GDPR and HIPAA.

Mitigation Strategies

Apply the latest security patches or updates for the arm-smmu-v3 component to fix the use-after-free vulnerability. Monitor vendor advisories for patches and test updates in a controlled environment before deployment.
