CVE-2018-19407 describes a denial-of-service vulnerability in the Linux kernel, specifically affecting the vcpu_scan_ioapic function in arch/x86/kvm/x86.c. This flaw, present in Linux kernel versions through 4.19.2 and impacting Canonical and Ubuntu Linux distributions, allows a local user to trigger a NULL pointer dereference and system crash through specially crafted system calls. With a CVSS score of 5.5 (Medium), it requires local access and low attack complexity, leading to high availability impact without affecting confidentiality or integrity. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or inclusion in the CISA KEV catalog, though it has received minimal community discussion and media coverage.
