AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a possible escalation of privilege in the display component caused by a missing bounds check.
It means that if a malicious actor already has System privilege, they could exploit this flaw to gain higher privileges locally without needing any user interaction.
How can this vulnerability impact me? :
The impact of this vulnerability is a local escalation of privilege, allowing an attacker who already has System privileges to potentially increase their level of access or control on the affected system.
