Vulnerability from fkie_nvd - Published: 2024-04-17 16:15 - Updated: 2026-06-17 07:18
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: fix performance regression in swap operation
The patch "netfilter: ipset: fix race condition between swap/destroy
and kernel side add/del/test", commit 28628fa9 fixes a race condition.
But the synchronize_rcu() added to the swap function unnecessarily slows
it down: it can safely be moved to destroy and use call_rcu() instead.
Eric Dumazet pointed out that simply calling the destroy functions as
rcu callback does not work: sets with timeout use garbage collectors
which need cancelling at destroy which can wait. Therefore the destroy
functions are split into two: cancelling garbage collectors safely at
executing the command received by netlink and moving the remaining
part only into the rcu callback.
