Possible memory leak or kernel exceptions caused by reading kernel heap data after free or NULL pointer dereference kernel exception.

Possible kernel exceptions caused by reading and writing kernel heap data after free.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions.

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 The shader code contained in the web page executes a path in the compiler that held onto an out of date pointer, pointing to a freed memory object.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 may conduct GPU system calls to read and write freed physical memory from the GPU.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions.

Software installed and run as a non-privileged user may conduct GPU system calls to read and write freed physical memory from the GPU.

Software installed and run as a non-privileged user may conduct improper GPU system calls to achieve unauthorised reads and writes of physical memory from the GPU HW.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions.

Software installed and run as a non-privileged user may conduct GPU system calls to read and write freed physical memory from the GPU.

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of reference counting to cause a potential use after free. Improper reference counting on an internal resource caused scenario where potential for use after free was present.

Software installed and run as a non-privileged user may conduct improper GPU system calls to corrupt kernel heap memory.

Software installed and run as a non-privileged user may conduct improper GPU system calls to corrupt kernel heap memory.

A web page that contains unusual WebGPU content loaded into the GPU GLES render process and can trigger write UAF crash in the GPU GLES user-space shared library. On certain platforms, when the process executing graphics workload has system privileges this could enable subsequent exploit on the system.

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger reads of stale data that can lead to kernel exceptions and write use-after-free. The Use After Free common weakness enumeration was chosen as the stale data can include handles to resources in which the reference counts can become unbalanced. This can lead to the premature destruction of a resource while in use.

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of resources reference counting creating a potential use after free scenario. Improper resource management and reference counting on an internal resource caused scenario where potential write use after free was present.
