Last modified
CVE-2018-14641 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 2.86% chance of exploitation in the next 30 days.
