CVE-2022-23089: Freebsd

Medium severity, CVSS 4.7. EPSS: 0.2% chance of exploitation in the next 30 days.

When dumping core and saving process information, proc_getargv() might return an sbuf which have a sbuf_len() of 0 or -1, which is not properly handled. An out-of-bound read can happen when user constructs a specially crafted ps_string, which in turn can cause the kernel to crash.
