CVE-2021-39639

In TBD of fvp.c, there is a possible way to glitch CPU behavior due to a missing permission check. This could lead to local escalation of privilege with physical access to device internals with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-198291476References: N/A
