CVE-2023-28537

Memory corruption while allocating memory in COmxApeDec module in Audio.

CVE-2023-28577

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.

CVE-2023-28575

The cam_get_device_priv function does not check the type of handle being returned (device/session/link). This would lead to invalid type usage if a wrong handle is passed to it.

CVE-2023-28576

The buffer obtained from kernel APIs such as cam_mem_get_cpu_buf() may be readable/writable in userspace after kernel accesses it. In other words, user mode may race and modify the packet header (e.g. header.count), causing checks (e.g. size checks) in kernel code to be invalid. This may lead to ou...
