AI-suggested
A fix is available in Linux kernel version 5.16 and later, which removes the 'auto_queue' feature and modifies the QRTR client driver to manage RX buffers manually. Users should upgrade to version 5.16 or later to remediate this issue.
Description
A race condition in the Linux kernel's MHI stack 'auto_queue' feature for IPCR DL channels could lead to NULL pointer dereference due to premature callback invocation before client driver initialization. This affects the QRTR client driver on certain Qualcomm machines and can cause boot issues. The vulnerability is fixed by removing the 'auto_queue' feature and requiring manual RX buffer management by the client driver.
