Red Hat recommends avoiding the installation or rebuilding of source RPMs from untrusted or unverified sources. Users should ensure only trusted source RPMs are processed to mitigate this vulnerability.
Description
CVE-2026-95521 is a command injection vulnerability in the rpm tool on Red Hat Enterprise Linux 10. It occurs when installing or rebuilding a source RPM with source or spec file basenames containing a %() macro, causing rpm to execute attacker-controlled shell commands via popen(). This allows arbitrary command execution as the invoking user, typically non-root, when processing untrusted source RPMs. Exploitation requires local user interaction to install or rebuild the malicious source RPM. The vulnerability is not exposed as a network service.
