In the Linux kernel, the following vulnerability has been resolved:
gpio: aggregator: fix a potential use-after-free
On error we free aggr->lookups->dev_id before removing the entry from
the lookup table. If a concurrent thread calls gpiod_find() before we
remove the entry, it could iterate over the list and call
gpiod_match_lookup_table() which unconditionally dereferences dev_id
when calling strcmp(). Reverse the order of cleanup.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
