Descriptions
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: set dormant flag on hook register failure
We need to set the dormant flag again if we fail to register
the hooks.
During memory pressure hook registration can fail and we end up
with a table marked as active but no registered hooks.
On table/base chain deletion, nf_tables will attempt to unregister
the hook again which yields a warn splat from the nftables core.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfilter: nf_tables: establece el indicador inactivo en caso de error en el registro del enlace. Necesitamos configurar el indicador inactivo nuevamente si no logramos registrar los enlaces. Durante la presión de la memoria, el registro de ganchos puede fallar y terminamos con una tabla marcada como activa pero sin ganchos registrados. Al eliminar la tabla/cadena base, nf_tables intentará cancelar el registro del gancho nuevamente, lo que genera un símbolo de advertencia desde el núcleo de nftables.
