- Summary
- gpio: aggregator: fix a potential use-after-free
- Details
-
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.
