CVE-2024-35898 HIGH

Published: 2024-05-19 | Last Modified: 2026-08-04 | Status: Modified

Description

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: Fix potential data-race in __nft_flowtable_type_get() nft_unregister_flowtable_type() within nf_flow_inet_module_exit() can concurrent with __nft_flowtable_type_get() within nf_tables_newflowtable(). And thhere is not any protection when iterate over nf_tables_flowtables list in __nft_flowtable_type_get(). Therefore, there is pertential data-race of nf_tables_flowtables list entry. Use list_for_each_entry_rcu() to iterate over nf_tables_flowtables list in __nft_flowtable_type_get(), and use rcu_read_lock() in the caller nft_flowtable_type_get() to protect the entire type query process.

Additional Descriptions (1)

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nf_tables: corrige una posible ejecución de datos en __nft_flowtable_type_get() nft_unregister_flowtable_type() dentro de nf_flow_inet_module_exit() puede coincidir con __nft_flowtable_type_get() dentro de nf_tables_newflowtable(). Y no hay ninguna protección cuando se itera sobre la lista nf_tables_flowtables en __nft_flowtable_type_get(). Por lo tanto, existe una posible ejecución de datos de la entrada de la lista nf_tables_flowtables. Utilice list_for_each_entry_rcu() para iterar sobre la lista nf_tables_flowtables en __nft_flowtable_type_get() y utilice rcu_read_lock() en el llamador nft_flowtable_type_get() para proteger todo el proceso de consulta de tipos.
