A web page that contains unusual GPU shader code is loaded from the Internet into the GPU compiler process triggers a write use-after-free crash in the GPU shader compiler library. On certain platforms, when the compiler process has system privileges this could enable further exploits on the device. The shader code contained in the web page executes a path in the compiler that held onto an out of date pointer, pointing to a freed memory object.

Software installed and run as a non-privileged user can trigger the GPU kernel driver to write to arbitrary read-only system files that have been mapped into application memory.

Software installed and run as a non-privileged user may conduct improper GPU system calls to gain write permission to read-only wrapped user-mode memory. This is caused by improper handling of the memory protections for the user-mode wrapped memory resource.

Software installed and run as a non-privileged user may conduct ptrace system calls to issue writes to GPU origin read only memory.

Software installed and run as a non-privileged user may conduct improper GPU system calls to allow unprivileged access to arbitrary physical memory page.

Software installed and run as a non-privileged user may conduct improper GPU system calls to gain write permissions to memory buffers exported as read-only. This is caused by improper handling of the memory protections for the buffer resource.

Software installed and running inside a Guest VM may conduct improper GPU system calls to prevent other Guests from running work on the GPU.

Software installed and run as a non-privileged user may conduct improper GPU system calls to issue reads and writes to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform, altering their behaviour.

Software installed and run as a non-privileged user may conduct improper GPU system calls to subvert GPU HW to write to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform altering their behaviour.

Software installed and run as a non-privileged user may conduct improper GPU system calls to subvert GPU HW to write to arbitrary physical memory pages.

Improper permission settings for mobile applications (com.transsion.carlcare) may lead to user password and account security risks.

An issue in Ruijie RG-NBS2009G-P RGOS v.10.4(1)P2 Release(9736) allows a remote attacker to gain privileges via the system/config_menu.htm.
