The version of the Mali GPU Kernel Driver installed on the remote system is prior to r44p1 or r45p0 running on Valhall or 5th Gen architecture. It is, therefore affected by a improper memory access vulnerability. A local non-privileged user can make improper GPU processing operations to access a limited amount outside of buffer bounds or to exploit a software race condition. If the systemβs memory is carefully prepared by the user, then this in turn could give them access to already freed memory.
Note that Nessus has not tested for this issue but has instead relied only on the applicationβs self-reported version number.
