Libevent: Prior to 2.1.13 and 2.2.2-a ...) (CVE-2026-63382)
A vulnerability exists in the libevent event notification library affecting specific stable versions prior to 2.1.13 and 2.2.2-a. The issue impacts multiple Ubuntu LTS versions, including 14.04 through 26.04. The CVSS 4.0 vector indicates network attack vector with low privileges required and partial attack complexity, resulting in medium severity. No known exploits are reported in the wild. No explicit patch or remediation information is provided in the source data.
AI Analysis
Technical Summary
Libevent versions prior to 2.1.13 and 2.2.2-a contain a vulnerability identified as CVE-2026-63382. The vulnerability affects multiple stable releases, including various Ubuntu-specific builds of version 2.0.21-stable and 2.1.8-stable through 2.1.12-stable. The CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:L/SI:L/SA:N) indicates a network attack vector with low attack complexity, no privileges or user interaction required, and high impact on confidentiality and integrity, but low impact on availability. The vulnerability is classified as medium severity. There is no vendor advisory or patch link provided in the data, and no known exploits in the wild have been reported.
Potential Impact
The vulnerability allows an attacker to potentially impact confidentiality and integrity of the affected systems remotely without requiring privileges or user interaction. The attack complexity is low, meaning it is relatively straightforward to exploit. The availability impact is low, indicating limited disruption to service. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor official libevent and Ubuntu security advisories for updates. Until a fix is available, consider mitigating exposure by limiting network access to affected services using libevent.
