CVE-2022-3524 is a memory-leak vulnerability in the Linux kernel IPv6 handler's ipv6_renew_options function. The flaw is triggered through setsockopt processing involving the IPV6_ADDRFORM and IPV6_DSTOPTS socket options. Under the reported trigger condition, a local process uses IPV6_ADDRFORM while other processes use IPV6_DSTOPTS, causing unreleased kernel memory and potentially destabilizing the system.
