"The version of the Mali GPU Kernel Driver installed on the remote system is prior to r38p2 or r40p0 running on Valhall
architecture. It is, therefore affected by an improper memory access vulnerability. A non-privileged user can make
improper GPU memory processing operations to gain write access to read-only memory, or obtain access to already freed
memory.

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