Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
netfilter: flowtable: publish GC-visible tuple last<br />
<br />
nf_flow_table_iterate() only treats original-direction tuple nodes as<br />
owning entries. Publishing the original node first lets GC observe and<br />
free a flow while flow_offload_add() is still inserting the reply node.<br />
Publish the reply node first and the original node last so GC never<br />
sees a partially installed flow.<br />
<br />
KASAN can trigger slab-use-after-free read and write reports in the<br />
flowtable/rhashtable path (rht_deferred_worker, jhash, flow_offload_del,<br />
flow_offload_lookup, etc.).
