How severe is CVE-2024-53197?

CVE-2024-53197 has a CVSS score of 7.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2024-53197?

CVE-2024-53197 affects the following packages: Kernel (Linux). Ecosystems affected: Linux.

How do I fix CVE-2024-53197?

Update Kernel to 4.19.325 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-53197 is resolved across your whole dependency graph.

How do I detect CVE-2024-53197 in my Linux dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Kernel, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-53197 if there is no patch (or I can't update yet)?

Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

Is CVE-2024-53197 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-53197 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-53197?

CVE-2024-53197 has an EPSS (Exploit Prediction Scoring System) score of 4.1%, placing it in the 91th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Is CVE-2024-53197 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2024-53197 (Linux Kernel Out-of-Bounds Access Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2025-04-09. CISA required all US federal civilian agencies to remediate this vulnerability by 2025-04-30. The required action was: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2024-53197?

CVE-2024-53197 is classified as Out-of-bounds Write (CWE-787). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2024-53197 published, and has it been updated?

CVE-2024-53197 was published on December 27, 2024 and was last updated on October 20, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

In the Linux kernel, the following vulnerability has been resolved:

ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices

A bogus device can provide a bNumConfigurations value that exceeds the initial value used in usb_get_configuration for allocating dev->config.

This can lead to out-of-bounds accesses later, e.g. in usb_destroy_configuration.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatImportant

This CVE marked as important vulnerability because it allows a malicious or compromised USB device to trigger out-of-bounds memory accesses in the Linux kernel’s ALSA USB audio subsystem. This occurs due to improper handling of bNumConfigurations, which can lead to memory corruption or even privilege escalation if…

Workaround published by Red Hat

To mitigate this issue, prevent module snd-usb-audio from being loaded. As the snd_usb_audio module will be auto-loaded when a usb device is hot plugged, the module can be prevented by loading with the following instructions: # echo "install snd_usb_audio /bin/true" >> /etc/modprobe.d/disable-snd-usb-audio.conf The system will need to be restarted if the modules are loaded. In most circumstances, the sound kernel modules will be unable to be unloaded while any programs are active and the device are in use. If the system requires this module to work correctly, this mitigation may not be suitable. If you need further assistance, see KCS article https://access.redhat.com/solutions/41278 or…
