Red Hat rpm. A local attacker: code execution
High7.0CVE-2026-84233 · Published Sep 1, 2026 · updated Sep 4, 2026
A flaw was found in rpm. A local attacker could supply a specially crafted `.gem` filename containing RPM macro syntax. When a user or automated workflow invokes `rpmuncompress -x` on this file, the macro expansion occurs during command construction. This allows the attacker to execute arbitrary commands with the privileges of the invoking account, leading to a compromise of confidentiality, integrity, and availability.
