CVE-2025-68180 Vulnerability Summary

CVE-2025-68180: In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix NULL deref in debugfs odm_combine_segments When a connector is connected but inactive (e.g., disabled by desktop environments), pipe_ctx->stream_res.tg will be destroyed. Then, reading odm_combine_segments causes kernel NULL pointer dereference.

Assessing the Risk of CVE-2025-68180

Access Complexity Graph

The exploitability of CVE-2025-68180 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-2025-68180

No exploitability data is available for CVE-2025-68180.

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-2025-68180, 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.
