What is CVE-2026-84233?

A vulnerability exists in RPM where a local attacker can craft a .gem filename containing specific RPM macro syntax. This issue arises when the command rpmuncompress -x is executed on such a file, leading to macro expansion during the command's construction. This opens up the potential for the attacker to execute arbitrary commands with the privileges of the user or automated workflow that invokes the command, thereby compromising the system's confidentiality, integrity, and availability.
