Vulnerability Title
Multiple Dmabuf Kernel Address UAF Vulnerability
Source: NVD (National Vulnerability Database)
Vulnerability Description
In the function call related to CAM_REQ_MGR_RELEASE_BUF there is no check if the buffer is being used. So when a function called cam_mem_get_cpu_buf to get the kernel va to use, another thread can call CAM_REQ_MGR_RELEASE_BUF to unmap the kernel va which cause UAF of the kernel address.
