CVE-2022-3524: Linux Kernel IPv6 ipv6_renew_options memory leak

First published: Wed Oct 12 2022(Updated: )

A memory leak flaw was found in the Linux kernel’s IPv6 functionality in how a user triggers the setsockopt of the IPV6_ADDRFORM and IPV6_DSTOPTS type. This flaw allows a user to crash the system if the setsockopt function is being called simultaneously with the IPV6_ADDRFORM type and other processes with the IPV6_DSTOPTS type. This issue is unlikely to happen unless a local process triggers IPV6_ADDRFORM.
