CVE-2023-4015 is a use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component, affecting various Debian and Linux kernel versions. This flaw allows a local attacker to achieve privilege escalation by exploiting an error during nftables rule building, where deactivating immediate expressions can lead to the unbinding of chains and subsequent use of deactivated objects. With a CVSS score of 7.8 (HIGH), the vulnerability has low attack complexity and requires local privileges, but can result in high impact to confidentiality, integrity, and availability. Currently, there is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
