Rocky Linux recently pushed out multiple security advisories that target core kernel files alongside the MySQL 8.0 module. System administrators running Rocky Linux SIG Cloud 8 need to install a critical kernel patch immediately because the flaws could allow unauthorized access or cause unexpected crashes. A separate important update addresses similar kernel weaknesses in the Cloud 9 environment while another moderate advisory fixes issues within the mecab and mysql modules on standard Rocky Linux 8 installations.
