CVE-2024-27017
Status: ModifiedMedium (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_pipapo: walk over current view on netlink dump
The generation mask can be updated while netlink dump is in progress. The pipapo set backend walk iterator cannot rely on it to infer what view of the datastructure is to be used. Add notation to specify if user wants to read/update the set.
Based on patch from Florian Westphal.
