In the Linux kernel, the following vulnerability has been resolved:
net: sparx5: free the matchall entry on destroy
sparx5_tc_matchall_replace() allocates a struct sparx5_mall_entry for
every offloaded matchall filter and adds it to sparx5->mall_entries.
sparx5_tc_matchall_destroy() removes the entry from the list, but never
frees it, so the entry of every deleted mirror and goto matchall filter
is leaked.
Free the entry after unlinking it.
The leak was discovered by an AI code review agent, and reproduced with
kmemleak on a lan969x EV board (EV23X71A) by repeatedly adding and
deleting matchall mirror and goto filters. With the fix, kmemleak no
longer reports the leak.
