- Summary
- CVE-2026-45897 affecting package kernel 6.6.150.1-1
- Details
-
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.
