NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-doc package and not the kernel-rt-doc package as distributed by Centos.

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: do not allow CHAIN_ID to refer to another table

When doing lookups for chains on the same batch by using its ID, a chain from a different table can be used. If a rule is added to a table but refers to a chain in a different table, it will be linked to the chain in table2, but would have expressions referring to objects in table1.

Then, when table1 is removed, the rule will not be removed as its linked to a chain in table2. When expressions in the rule are processed or removed, that will lead to a use-after-free.

When looking for chains by ID, use the table that was used for the lookup by name, and only return chains belonging to that same table.
