In the context of computing, an unqualified call refers to a function call that does not specify the library in which the function resides. If a user has the authority to compile or restore a program, this unqualified call could be manipulated to make the <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-5491-acer-controlcenter-remote-code-execution-vulnerability-potential-system-compromise\/\"  data-wpil-monitor-id=\"61264\">system carry out user-controlled code<\/a>.
