NVD Description

Note: Versions mentioned in the description apply only to the upstream rtla package and not the rtla package as distributed by AlmaLinux. See How to fix? for AlmaLinux:10 relevant fixed versions and status.

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

netfilter: flowtable: publish GC-visible tuple last

nf_flow_table_iterate() only treats original-direction tuple nodes as owning entries. Publishing the original node first lets GC observe and free a flow while flow_offload_add() is still inserting the reply node. Publish the reply node first and the original node last so GC never sees a partially installed flow.

KASAN can trigger slab-use-after-free read and write reports in the flowtable/rhashtable path (rht_deferred_worker, jhash, flow_offload_del, flow_offload_lookup, etc.).
