CVE-2018-6554 describes a memory leak vulnerability in the Linux kernel, specifically within the IrDA networking subsystem (af_irda.c), affecting various Canonical, Debian, and Linux distributions before kernel version 4.17. An authenticated local attacker can trigger this by repeatedly binding an AF_IRDA socket, leading to memory exhaustion and a denial of service. Rated as Medium severity (CVSS 5.5), this vulnerability has a low attack complexity and requires local access, with the primary impact being system unavailability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
