CVE-2026-84233 | BDVDB-2026-367148 Detail

Red HatRed Hat Hardened Images

Description#

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.

Impact#

Per CVSS v3.1: confidentiality impact high, integrity impact high, availability impact high. Attack vector: local.

Weaknesses#

  • CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
