Description
Description
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_counter: serialize reset with spinlock
Add a global static spinlock to serialize counter fetch+reset
operations, preventing concurrent dump-and-reset from underrunning
values.
The lock is taken before fetching the total so that two parallel
resets cannot both read the same counter values and then both
subtract them.
A global lock is used for simplicity since resets are infrequent.
If this becomes a bottleneck, it can be replaced with a per-net
lock later.
