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