CVE-2024-43820 Vulnerability Summary

CVE-2024-43820: In the Linux kernel, the following vulnerability has been resolved: dm-raid: Fix WARN_ON_ONCE check for sync_thread in raid_resume rm-raid devices will occasionally trigger the following warning when being resumed after a table load because DM_RECOVERY_RUNNING is set: WARNING: CPU: 7 PID: 5660 at drivers/md/dm-raid.c:4105 raid_resume+0xee/0x100 [dm_raid] The failing check is: WARN_ON_ONCE(test_bit(MD_RECOVERY_RUNNING, &mddev->recovery)); This check is designed to make sure that the sync thread isn't registered, but md_check_recovery can set MD_RECOVERY_RUNNING without the sync_thread ever getting registered. Instead of checking if MD_RECOVERY_RUNNING is set, check if sync_thread is non-NULL.

Assessing the Risk of CVE-2024-43820

Access Complexity Graph

The exploitability of CVE-2024-43820 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-2024-43820

No exploitability data is available for CVE-2024-43820.

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-2024-43820, 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-2024-43820, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
