In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Fix use-after-free in find_pos_and_ways() error path
The error path releases its reference to a switch decoder before logging an error that includes the decoder name. If the released reference is the last one, the decoder can be freed before the error message accesses its name.
Drop the reference after the error is reported.
