CVE-2024-53197 Linux CVE debrief

CVE-2024-53197 is a Linux kernel out-of-bounds access vulnerability that CISA added to its Known Exploited Vulnerabilities catalog on 2025-04-09. Because it is on the KEV list, defenders should treat it as actively exploited or otherwise significant enough to require prompt mitigation, even though the provided corpus does not include a CVSS score or detailed impact analysis. The most important action is to identify affected Linux kernel deployments and apply vendor guidance as soon as possible.

Who should care

Linux distribution maintainers, kernel-integrated product vendors, cloud and container platform operators, fleet administrators, and security teams responsible for Linux-based systems should review this CVE. Any environment running Linux kernel builds from affected distributions should be prioritized because CISA has listed the issue in KEV.

Technical summary

The provided source corpus identifies the issue as a Linux Kernel out-of-bounds access vulnerability. No further technical breakdown, affected subsystem, exploit conditions, or remediation specifics are included in the supplied materials. The main evidence available is CISA’s KEV entry, which marks the vulnerability as a known exploited weakness and points to the Linux kernel CVE announcement, the Android security bulletin, and the NVD record for additional details.

Defensive priority

High. The KEV designation indicates immediate defensive attention is warranted. Even without a CVSS score in the provided data, KEV-listed issues should be triaged quickly, with emphasis on patching, mitigation, and exposure reduction before the KEV due date of 2025-04-30.

Recommended defensive actions

  • Inventory Linux kernel versions across servers, endpoints, containers, and embedded devices.
  • Check vendor advisories and package updates for the affected kernel line and apply the latest supported fixes.
  • If patching is delayed, follow vendor mitigation guidance and reduce exposure where feasible.
  • Prioritize internet-facing, privileged, and high-value systems first.
  • For cloud services, follow applicable CISA BOD 22-01 guidance.
  • If no mitigation is available for a given deployment, plan to discontinue use or isolate the affected product until a fix is deployed.

Evidence notes

The available evidence is limited to the KEV catalog entry and its metadata. The corpus states the vulnerability name as 'Linux Kernel Out-of-Bounds Access Vulnerability,' lists the vendor project as Linux and product as Kernel, and records CISA KEV dateAdded as 2025-04-09 with dueDate 2025-04-30. The corpus also references the Linux kernel CVE announcement, the Android security bulletin, and the NVD record, but no additional details from those sources are included here. No CVSS score is provided in the supplied data.
