CVE-2026-2625

A flaw was found in rust-rpm-sequoia. An attacker can exploit this vulnerability by providing a specially crafted Red Hat Package Manager (RPM) file. During the RPM signature verification process, this crafted file can trigger an error in the OpenPGP signature parsing code, leading to an unconditional termination of the rpm process. This issue results in an application level denial of service, making the system unable to process RPM files for signature verification.

This MODERATE impact application level denial of service vulnerability. A specially crafted RPM file can trigger a Rust panic during OpenPGP signature verification, causing the rpm process to abort. This issue can be exploited without privileges or user interaction by processing a malicious RPM file, for example, via rpm -Kv or rpm --checksig.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Avoid processing untrusted or attacker-controlled RPM files with rpm -Kv or rpm --checksig. Use isolated environments or additional validation layers when handling untrusted RPM artifacts.
