A vulnerability has been identified in the Linux kernel regarding the validation of the doorbell_offset parameter during user queue creation in amdgpu. Lack of proper bounds checking may lead to corruption of the doorbell space in the kernel.

A vulnerability related to sync handling in amdgpu has been resolved in the Linux kernel. Invalidating a dmabuf can impact other users of the shared buffer object (BO).

A vulnerability in the Linux kernel related to amdgpu has been resolved, which occurred under low memory conditions. In such situations, the kmalloc function could fail, requiring the mutex to be unlocked for a clean exit.
