CVE-2022-2586: (Pwn2Own) Linux Kernel nft_object Use-After-Free Privilege Escalation Vulnerability
First published: Wed Aug 03 2022(Updated: )
A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation.
