Moby is an open source container framework. In Docker Engine prior to version 29.5.1, Docker Daemon versions 28.5.2 and prior, and Moby Daemon prior to version 2.0.0-beta.14, a race condition during docker cp mount setup allows a malicious container to redirect a bind mount target to an arbitrary host path, potentially overwriting host files or causing denial of service. This issue has been patched in Docker Engine version 29.5.1 and Moby Daemon version 2.0.0-beta.14.

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-1e56ab167d advisory.

    Multiple vulnerabilities were discovered in the Docker container engine     and in the bundled BuildKit build toolkit, which may result in privilege     escalation, arbitrary file access on the host, or bypass of authorization     policies.

    For the stable distribution (trixie), these problems have been fixed in     version 26.1.5+dfsg1-9+deb13u1.

    We recommend that you upgrade your docker.io packages.

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:68334 advisory.

    Red Hat Edge Manager (RHEM) provides simple, scalable, and security-focused     management of edge devices and applications. It supports image-mode RHEL and     container workloads that run on Podman/Docker or Kubernetes.

    RHEM is now available as a standalone feature, providing greater flexibility for     edge deployments. In addition to the standalone version, RHEM continues to be     offered as a plugin for the following platforms:

    Red Hat Advanced Cluster Management (RHACM): Extends fleet management to edge     devices.
    Red Hat Ansible Automation Platform (AAP): Integrates edge management with     Ansible automation.

    This integration enables organizations to optimize the management and     orchestration of their fleets of edge devices; whether its thousands of     dispersed retail point-of-sale systems or industrial machinery on remote factory     floors.

    Value for customers and partners:

    * This solution not only helps customers manage thousands of devices but helps     scale operations.
    * To manage large-scale deployments, customers need to be able to integrate with     their existing management systems, support remote configuration and over-the-air     updates, and collect telemetry data for advanced analytics.
    * Red Hat Edge Manager offers a simple and security-focused lifecycle     management, from onboarding to decommissioning of edge devices.

    This complete end-to-end solution empowers organizations to gain the most value     from the fleets of devices that generate data, all from a centralized location.

    Security Fixes:

The version of docker installed on the remote host is prior to 25.0.16-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2ECS-2026-134 advisory.

    The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key     with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during     signature verification. This could be triggered by unauthenticated clients during public key     authentication. RSA moduli are now limited to 8192 bits, and DSA parameters are validated per FIPS 186-2.
    (CVE-2026-39829)

    A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking     the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a     resource leak per connection. Unsolicited global responses are now discarded. (CVE-2026-39830)

    The Verify() method for FIDO/U2F security key types (sk-ecdsa-sha2-nistp256@openssh.com, sk-ssh-     ed25519@openssh.com) did not check the User Presence flag. Signatures generated without physical touch     were accepted, allowing unattended use of a hardware security key. To restore the previous behavior,     return a no-touch-required extension in Permissions.Extensions from PublicKeyCallback. (CVE-2026-39831)

    The in-memory keyring returned by NewKeyring() silently accepted keys with the ConfirmBeforeUse constraint     but never enforced it. The key would sign without any confirmation prompt, with no indication to the     caller that the constraint was not in effect. NewKeyring() now returns an error when unsupported     constraints are requested. (CVE-2026-39833)

    Docker: Race condition in docker cp allows bind mount redirection to host path (CVE-2026-42306)

    Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation. Now, both     the 'key' and 'key.SignatureKey' are checked for @revoked. (CVE-2026-42508)

    Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any     other type of callback is passed other than public key, then the source-address validation would be     skipped. (CVE-2026-46595)

    A norm.Iter can enter an infinite loop when handling input containing invalid UTF-8 bytes.
