CVE-2014-0155

CVE-2014-0155 describes a denial-of-service vulnerability in the Linux kernel, specifically affecting the KVM virtualization module. A guest OS user can crash the host OS by crafting a malicious entry in the I/O APIC redirection table, due to improper validation of a return value within the ioapic_deliver (later ioapic_service) function. This vulnerability has a CVSS score of 5.5, indicating a medium severity, and requires authenticated access to a guest OS (AV:A/Au:S) to achieve a complete host system compromise (A:C). There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
