Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2026-78367 - Priority: High - CVSS: n/a (important) - EPSS: 0.0020 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Sep 28, 2026 ## Description Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2026-84233: 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. CVE-2026-78367: A flaw was found in rpmbuild. When rpmbuild processes a crafted tarball in tarball mode, a specially designed tar member name can lead to macro injection. This vulnerability allows a remote attacker to execute arbitrary code on the system by convincing a user to build a malicious tarball. ## Where it's fixed | Platform | Product | Fixed in | Fix |
