CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:HSummary
CVE-2026-24834 is a critical-severity Incorrect Permission Assignment for Critical Resource (CWE-732) vulnerability in Katacontainers Kata Containers. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 13th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-16 (Security and Privacy Attributes) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

CVE-2026-24834 is a high-severity vulnerability (CVSS 9.3, CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H; CWE-732) in Kata Containers, an open source project implementing lightweight Virtual Machines designed to perform like containers. It affects versions prior to 3.27.0 and stems from an issue in Kata's integration with Cloud Hypervisor, where a container user can modify the file system used by the guest micro VM, enabling arbitrary code execution as root within that VM.
A local attacker with access to a vulnerable Kata container—no privileges, user interaction, or complex setup required—can exploit this to achieve full root compromise inside the guest micro VM. The changed scope (S:C) amplifies the impact on confidentiality, integrity, and availability within the VM. Exploitation does not affect the host system or other containers/VMs on the host, though arm64 QEMU's lack of NVDIMM read-only support may allow guest writes to reach the image file until upstream QEMU provides this capability.
Kata Containers version 3.27.0 fully patches the vulnerability. Security advisories recommend immediate upgrades to this version or later. Key resources include the patching commit (https://github.com/kata-containers/kata-containers/commit/6a672503973bf7c687053e459bfff8a9652e16bf), the 3.27.0 release notes (https://github.com/kata-containers/kata-containers/releases/tag/3.27.0), and the GitHub security advisory (https://github.com/kata-containers/kata-containers/security/advisories/GHSA-wwj6-vghv-5p64).

modify the file system used by the Guest micro VM ultimately achieving arbitrary code execution as root in said VM. The current understanding is this doesn’t impact the security of the Host or of other containers / VMs running on that Host (note that arm64 QEMU lacks NVDIMM read-only support: It is believed that until the upstream QEMU gains this capability, a guest write could reach the image file). Version 3.27.0 patches the issue.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the access control policy that defines permissions on resources, thereby stopping incorrect assignments from remaining exploitable.
Associating and preserving security attributes (including permissions) with objects reduces the chance they are lost or weakened on copy/restore/share.
Directly requires assignment of only the minimum necessary permissions, preventing overly broad grants on critical resources.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
By requiring owners to determine and document the exact permissions needed for each asset, the control reduces the likelihood that default or overly permissive file and resource permissions will be left in place.
Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.
Documented authorization, expiry rules, and audit logging of privileged accounts make it harder for critical resources to retain overly permissive or stale permission assignments.
Requiring explicit configuration of access controls and permissions for files, applications and services counters the assignment of overly permissive default or incorrect file-system rights.
Enforcing differentiated permissions on the source-code repository and program listings stops the assignment of overly broad default or inherited permissions to critical resources.
By defining and enforcing secure permission settings in configuration templates, the control reduces the likelihood that critical resources receive incorrect permission assignments.
