With a CVSS score of 7.2, this vulnerability is rated as high severity, allowing a local attacker to impact confidentiality, integrity, and availability with low attack complexity. While Oracle has not confirmed, third-party claims suggest multiple buffer overflows in the mysqlshow tool could be exploited by remote database servers via long table or database names. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
