CVE search metadata
CVE search record: CVE-2024-4911. Severity: medium. CVSS: 6.3. EPSS: 0.41%. KEV: no. Product: Enterprise Linux. Brief: Denial of Service and Data Manipulation Vulnerability in cjose Library. Brief link: https://feed.craftedsignal.io/briefs/2026-09-cjose-rhel-vuln/
A vulnerability has been identified in the cjose library, a component used within Red Hat Enterprise Linux. The flaw allows a remote, unauthenticated attacker to exploit improper input handling within the library, leading to a denial of service (DoS) condition or the potential manipulation of data processed by the library. This impact is significant as cjose is commonly involved in cryptographic operations and token handling. Defenders should prioritize patching affected RHEL systems, as the ability for remote, unauthenticated exploitation poses a high risk to both service availability and data integrity for applications relying on the library for secure communication. The issue is tracked as CVE-2024-4911.
Impact
The vulnerability poses a risk of service disruption and unauthorized modification of data integrity in systems running affected versions of Red Hat Enterprise Linux. Exploitation could allow an attacker to crash critical services or potentially alter data handled by cryptographic processes, impacting any sector relying on RHEL infrastructure for secure authentication or data exchange.
Recommendation
Prioritize the application of security patches provided by Red Hat for CVE-2024-4911 across all RHEL environments. Monitor security advisory portals for specific updated package versions for the cjose library.
