Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2018-14641
CWEhttps://cwe.mitre.org/data/definitions/456.html

A security flaw was found in the ip_frag_reasm() function in net/ipv4/ip_fragment.c in the Linux kernel from 4.19-rc1 to 4.19-rc3 inclusive, which can cause a later system crash in ip_do_fragment(). With certain non-default, but non-rare, configuration of a victim host, an attacker can trigger this crash remotely, thus leading to a remote denial-of-service.

Weakness

The product does not initialize critical variables, which causes the execution environment to use unexpected values.
