The version of the Mali GPU Kernel Driver installed on the remote system is prior to r42p0 running on Valhall or 5th Gen architecture. It is, therefore affected by an improper memory access vulnerability. A non-privileged user can make improper GPU memory processing operations to access a limited amount outside of buffer bounds.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
