Historical catalog analysis: CISA added this entry on April 09, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.
What the vulnerability is
CVE-2024-53150 is an out-of-bounds read vulnerability (CWE-125) located within the USB-audio driver of the Linux Kernel. This flaw enables a local attacker with privileged access to potentially obtain sensitive information from the system’s memory.
Exposure and applicability
This vulnerability affects systems running the Linux Kernel that utilize the USB-audio driver. Because this is a common open-source component, exposure extends across various distributions and products incorporating the affected kernel code. The attack vector is local, meaning the actor must already have a presence on the system and possess privileged permissions to exploit the flaw.
Remediation priorities
Given its inclusion in CISA’s Known Exploited Vulnerabilities (KEV) catalog as of April 9, 2025, this vulnerability should be prioritized for remediation. Our analysis suggests the following priority sequence:
- Asset Identification: Identify all Linux-based assets utilizing USB-audio hardware or drivers.
- Patch Deployment: Apply vendor-supplied mitigations and kernel updates as specified by the distribution maintainers.
- Cloud Service Review: For organizations utilizing cloud services, review applicable BOD 22-01 guidance to ensure service providers have addressed the underlying kernel exposure.
- Decommissioning: If a mitigation is unavailable for a legacy system that cannot be patched, consider discontinuing use of the affected product.
How to validate remediation
Verification must move beyond simple version checks to confirm that the vulnerability has been mitigated in the active runtime environment. We recommend the following validation approach:
- Kernel Version Verification: Confirm the running kernel version matches the patched release provided by the vendor.
- Driver State Analysis: Verify that the USB-audio driver is either updated to the secure version or, if the hardware is not required, that the driver has been disabled/blacklisted to reduce the attack surface.
- Configuration Audit: Ensure that privileged access controls are strictly enforced to limit the number of local accounts capable of interacting with kernel drivers.
Limits and open questions
A successful update reduces the likelihood of exploitation but does not eliminate all residual risk associated with local privileged access. It remains unknown whether this vulnerability has been utilized in specific ransomware campaigns. Furthermore, because the Linux Kernel is integrated into numerous third-party products, organizations must rely on individual vendor timelines for patch availability, which may vary across different hardware ecosystems.
