GHSA-4c46-9f7j-r9vq · Severity: unknown — In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_counter:...
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.
Conclusion & alert: CVE-2026-45897 is rated Low Risk (8.8/100): low exploitation likelihood (EPSS 0.19%). Mandatory action: Low composite risk—no urgent action required; patch on your normal maintenance cycle and revisit priority if CVSS or EPSS increases.
