CVE-2026-22775
Description
A flaw was found in devalue, a JavaScript library used for serializing values. A remote attacker could exploit this vulnerability by providing specially crafted input to the devalue.parse function. This improper input validation, specifically during the ArrayBuffer hydration process, can cause the application to consume excessive CPU time and memory. This ultimately leads to a denial of service (DoS), making the affected system unavailable to legitimate users.
Statement
This vulnerability is rated Important for Red Hat. The devalue JavaScript library, when used by applications to parse untrusted external input, is susceptible to a denial of service. Specially crafted input to the devalue.parse function can lead to excessive CPU and memory consumption, rendering the affected system unavailable. Red Hat products such as Red Hat Build of Podman Desktop and Red Hat Trusted Artifact Signer are affected if they process untrusted data using the vulnerable devalue.parse function.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Technical Impact: DoS: Amplification; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
Sometimes this is a factor in "flood" attacks, but other types of amplification exist.
