CVE-2025-38322 Vulnerability Summary

CVE-2025-38322: In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel: Fix crash in icl_update_topdown_event() The perf_fuzzer found a hard-lockup crash on a RaptorLake machine: Oops: general protection fault, maybe for address 0xffff89aeceab400: 0000 CPU: 23 UID: 0 PID: 0 Comm: swapper/23 Tainted: [W]=WARN Hardware name: Dell Inc. Precision 9660/0VJ762 RIP: 0010:native_read_pmc+0x7/0x40 Code: cc e8 8d a9 01 00 48 89 03 5b cd cc cc cc cc 0f 1f ... RSP: 000:fffb03100273de8 EFLAGS: 00010046 .... Call Trace: <TASK> icl_update_topdown_event+0x165/0x190 ? ktime_get+0x38/0xd0 intel_pmu_read_event+0xf9/0x210 __perf_event_read+0xf9/0x210 CPUs 16-23 are E-core CPUs that don't support the perf metrics feature. The icl_update_topdown_event() should not be invoked on these CPUs. It's a regression of commit: f9bdf1f95339 ("perf/x86/intel: Avoid disable PMU if !cpuc->enabled in sample read") The bug introduced by that commit is that the is_topdown_event() function is mistakenly used to replace the is_topdown_count() call to check if the topdown functions for the perf metrics feature should be invoked. Fix it.

Assessing the Risk of CVE-2025-38322

Access Complexity Graph

The exploitability of CVE-2025-38322 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-2025-38322

CVE-2025-38322 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.

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-2025-38322, 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.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2025-38322, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2025-38322 has no significant impact on data confidentiality.
  • Integrity: None
    CVE-2025-38322 poses no threat to data integrity.
  • Availability: High
    CVE-2025-38322 can disrupt system operations, potentially causing complete denial of service (DoS).
