A physically proximate attacker can trigger memory corruption by selecting a small number of 3-byte UTF-8 characters, leading to an "off-by-two memory error." The CVSS score of 4.7 indicates a medium severity, with an attack vector requiring local access and medium attack complexity, resulting in a complete denial of service. While not listed on the KEV catalog and with minimal community discussion or media coverage, an exploit for privilege escalation related to this vulnerability has been published on ExploitDB.
