ARM Mali GPU Kernel Driver < r30p0 / < r31p0 Use After Free (CVE-2021-29256)

high Nessus Plugin ID 178128

Synopsis

The remote host has a driver that is affected by a use-after-free error.

Description

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 a use-after-free error.
A non-privileged user can make improper operations on GPU memory to gain access to already freed memory and may be able to gain root privilege, and/or disclose information.

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

Solution

Upgrade to Mali GPU Kernel Driver r30p0, r31p0 or later.
