Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout<br />
<br />
While the rhashtable set gc runs asynchronously, a race allows it to<br />
collect elements from anonymous sets with timeouts while it is being<br />
released from the commit path.<br />
<br />
Mingi Cho originally reported this issue in a different path in 6.1.x<br />
with a pipapo set with low timeouts which is not possible upstream since<br />
7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set<br />
element timeout").<br />
<br />
Fix this by setting on the dead flag for anonymous sets to skip async gc<br />
in this case.<br />
<br />
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on<br />
transaction abort"), Florian plans to accelerate abort path by releasing<br />
objects via workqueue, therefore, this sets on the dead flag for abort<br />
path too.
