Overview
Multiple vulnerabilities have been reported in Google Android which could be exploited by an attacker to execute arbitrary code, obtain sensitive information or gain elevated privileges on the targeted system.
Description
These vulnerabilities exist in Google Android due to flaws in the Framework Component, Media Framework, System Component, Kernel Component, MediaTek components, Unisoc components, Qualcomm components and Qualcomm closed-sourcecomponents. These vulnerabilities could enable a local malicious application to bypass operating system protections that isolate application data from other applications and also bypass user interaction requirements to gain additional permissions; allows a local attacker to gain access to additional permissions using a specially crafted transmission. These may also allow a remote attacker to cause Denial of Service.
