Memory corruption in WLAN HAL while parsing Rx buffer in processing TLV payload.

Memory corruption in WLAN HAL while processing command parameters from untrusted WMI payload.

Memory corruption in WLAN handler while processing PhyID in Tx status handler.

Memory corruption in WLAN FW while processing command parameters from untrusted WMI payload.

Memory corruption in WLAN HAL while passing command parameters through WMI interfaces.

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.

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 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 w...
