Google fixed the zero-day Kernel Vulnerability, indicating the problem was not that serious.
A privilege escalation vulnerability was detected in the Linux Kernel a few days ago, affecting a large number of Android devices. Due to the fragmentation of the Android device system and the complicated channels of OEM manufacturers and operators, a large number of affected devices may not be corrected. Google has released a vulnerability fix patch for the Android device, indicating that the patch has been shared with the device manufacturer. It may take several weeks for a few manufacturers to push the patch to users. However, Google said it was okay, and the problem was not very serious. The affected devices were protected by SELinux. Only a few large Android OEMs will push security fixes. After purchasing many Android devices, you will not be updated.
