CVE-2025-22005 Vulnerability Summary

CVE-2025-22005: In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix memleak of nhc_pcpu_rth_output in fib_check_nh_v6_gw(). fib_check_nh_v6_gw() expects that fib6_nh_init() cleans up everything when it fails. Commit 7dd73168e273 ("ipv6: Always allocate pcpu memory in a fib6_nh") moved fib_nh_common_init() before alloc_percpu_gfp() within fib6_nh_init() but forgot to add cleanup for fib6_nh->nh_common.nhc_pcpu_rth_output in case it fails to allocate fib6_nh->rt6i_pcpu, resulting in memleak. Let's call fib_nh_common_release() and clear nhc_pcpu_rth_output in the error path. Note that we can remove the fib6_nh_release() call in nh_create_ipv6() later in net-next.git.

Assessing the Risk of CVE-2025-22005

Access Complexity Graph

The exploitability of CVE-2025-22005 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-2025-22005

No exploitability data is available for CVE-2025-22005.

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-2025-22005, 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.
