Qualcomm Multiple Chipsets Incorrect Authorization Vulnerability
Qualcomm · Multiple Chipsets
A memory corruption flaw in Qualcomm's multiple chipsets lies in the GPU micronode component, where unauthorized command execution occurs when a specific sequence of commands is run. An attacker with local access and no privileges can trigger it, but it requires user interaction, and successful exploitation can compromise confidentiality, integrity, and availability across a changed security scope.
