Description msiddiqu 2020-03-31 19:52:45 UTC

A vulnerability was found in sdcardfs in Kernel where there is a possible violation of the separation of data between profiles due to shared mapping of obb files. This could lead to local escalation of privilege with User execution privileges needed. User interaction is needed for exploitation.
