Ubuntu.comUB:CVE-2024-35898CVE-2024-35898
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.
