"The version of the Mali GPU Kernel Driver installed on the remote system is prior to r30p0 running on Bifrost or Valhall
architecture or prior to r31p0 running on Midgard architecture. It is, therefore affected by an improper memory access
vulnerability. A non-privileged user can get a write access to read-only memory, and may be able to gain root privilege,
corrupt memory and modify the memory of other processes.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
