Exploitability
| 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

Can you explain this vulnerability to me?
This vulnerability is a possible memory corruption issue caused by a use after free error in the display component.
A use after free occurs when a program continues to use memory after it has been freed, which can lead to unpredictable behavior or exploitation.
In this case, the vulnerability could allow a local escalation of privilege if a malicious actor already has System privilege.
No user interaction is needed to exploit this vulnerability.
How can this vulnerability impact me? :
If exploited, this vulnerability could allow an attacker who already has System privilege to escalate their privileges further locally.
This could lead to greater control over the affected system, potentially allowing the attacker to execute unauthorized actions or access sensitive information.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
