In the Linux kernel, the following vulnerability has been resolved:
slimbus: core: fix device reference leak on report present
Slimbus devices can be allocated dynamically upon reception of
report-present messages.
Make sure to drop the reference taken when looking up already registered
devices.
Note that this requires taking an extra reference in case the device has
not yet been registered and has to be allocated.
