CVSS: 7.0EPSS: 0%CPEs: 7EXPL: 0CVE-2024-27397 – netfilter: nf_tables: use timestamp to check for set element timeout
https://notcve.org/view.php?id=CVE-2024-27397
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: use timestamp to check for set element timeout Add a timestamp field at the beginning of the transaction, store it in the nftables per-netns area. Update set backend .insert, .deactivate and sync gc path to use the timestamp, this avoids that an element expires while control plane transaction is still unfinished. .lookup and .update, which are used from packet path, still use the current time to check if the element has expired. And .get path and dump also since this runs lockless under rcu read size lock. Then, there is async gc which also needs to check the current time since it runs asynchronously from a workqueue. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nf_tables: use la marca de tiempo para verificar el tiempo de espera del elemento establecido. Agregue un campo de marca de tiempo al comienzo de la transacción y guárdelo en el área nftables per-netns. • https://git.kernel.org/stable/c/c3e1b005ed1cc068fc9d454a6e745830d55d251d https://git.kernel.org/stable/c/f8dfda798650241c1692058713ca4fef8e429061 https://git.kernel.org/stable/c/eaf1a29ea5d7dba8e84e9e9f3b3f47d0cd540bfe https://git.kernel.org/stable/c/7b17de2a71e56c10335b565cc7ad238e6d984379 https://git.kernel.org/stable/c/0d40e8cb1d1f56a994cdd2e015af622fdca9ed4d https://git.kernel.org/stable/c/b45176b869673417ace338b87cf9cdb66e2eeb01 https://git.kernel.org/stable/c/383182db8d58c4237772ba0764cded4938a235c3 https://git.kernel.org/stable/c/7395dfacfff65e9938ac0889dafa1ab01 •

In the Linux kernel, the following vulnerability has been resolved: net: gtp: Fix Use-After-Free in gtp_dellink Since call_rcu, which is called in the hlist_for_each_entry_rcu traversal of gtp_dellink, is not part of the RCU read critical section, it is possible that the RCU grace period will pass during the traversal and the key will be free. To prevent this, it should be changed to hlist_for_each_entry_safe.
