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 cause mismanagement of resources creating a write use after free scenario. A shared resource (memory page) managed by a CPU thread of control (driver) and accessed by a GPU thread of control (Firmware) can cause a write UAF when the CPU thread frees the resource before the GPU FW has finished accessing it.

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an error path leading to UAF of GPU page tables. The vulnerability allows physical memory allocated for MMU page tables to be used after being freed. This was caused by an error path that would not cleanup properly before freeing the physical allocation.

On certain platforms, when the process executing graphics workload has system privileges this could enable further exploits on the device.

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.

A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers.

In the Linux kernel, the following vulnerability has been resolved: crypto: sun8i-ce - Fix use after free in unprepare sun8i_ce_cipher_unprepare should be called before crypto_finalize_skcipher_request, because client callbacks may immediately free memory, that isn't needed anymore. But it will be used by unprepare after free. Before removing prepare/unprepare callbacks it was handled by crypto engine in crypto_finalize_request.
