In the Linux kernel, the following vulnerability has been resolved:

accel/qaic: Address potential out-of-bounds read in resp_worker()

Although 'commit 2feec5ae5df7 ("accel/qaic: Handle DBC deactivation if the owner went away")' fixes the scenario it was intended for by walking the message and only decoding QAIC_TRANS_DEACTIVATE_FROM_DEV, if present, it skipped over the bounds checking code that is included in decode_message(). This could lead to issues such as reading past the slab allocation's end, infinite loops or kernel panics. For those issues to happen, a malformed wire message is needed to be sent from the device.

Instead of duplicating the bounds checking code already present in decode_message(), use the function inside resp_worker().
