CVE-2025-22119 Vulnerability Summary

CVE-2025-22119: In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: init wiphy_work before allocating rfkill fails syzbort reported a uninitialize wiphy_work_lock in cfg80211_dev_free. [1] After rfkill allocation fails, the wiphy release process will be performed, which will cause cfg80211_dev_free to access the uninitialized wiphy_work related data. Move the initialization of wiphy_work to before rfkill initialization to avoid this issue. [1] INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe you didn't initialize this object before use? turning off the locking correctness validator.

Assessing the Risk of CVE-2025-22119

Access Complexity Graph

The exploitability of CVE-2025-22119 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2025-22119

No exploitability data is available for CVE-2025-22119.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-22119, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
