Upgrade Rocky-Linux:8 kernel-doc to version 0:4.18.0-553.5.1.el8_10 or higher.
This issue was patched in RLSA-2024:3618.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-doc package and not the kernel-doc package as distributed by Rocky-Linux.
See How to fix? for Rocky-Linux:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout
While the rhashtable set gc runs asynchronously, a race allows it to collect elements from anonymous sets with timeouts while it is being released from the commit path.
Mingi Cho originally reported this issue in a different path in 6.1.x with a pipapo set with low timeouts which is not possible upstream since 7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set element timeout").
Fix this by setting on the dead flag for anonymous sets to skip async gc in this case.
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on transaction abort"), Florian plans to accelerate abort path by releasing objects via workqueue, therefore, this sets on the dead flag for abort path too.
