Summary
[none]
Details

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

Due to a race condition between nftables netlink control plane transaction and nftset element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability.

We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8.
