The version of the Mali GPU Kernel Driver installed on the remote system is prior to r41p0 running on Midgard, Bifrost or Valhall architecture. It is, therefore affected by a use-after-free error. A non-privileged user can make improper GPU processing operations to gain 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.
