CVE-2026-92574

A flaw was found in CRI-O's `bind_mount_prefix` handling. When configured with a non-empty prefix, a malicious container or local attacker could use a hostPath containing an intermediate absolute symlink, causing the bind mount source to resolve outside the intended prefixed root.

A trust-boundary flaw in CRI-O's sandbox state persistence allows attacker-influenced pod metadata to overwrite CRI-O's own reserved sandbox bookkeeping; once reloaded as trusted after a restart, a later container recreate in that sandbox can expose a host-side runtime-management resource inside the container, enabling container escape.

A vulnerability in CRI-O related to the container checkpoint and restore feature. When CRI-O is configured to restore containers from checkpoint archives, insufficient validation of restore metadata may allow a user with sufficient privileges to perform unintended operations on the host filesystem.

CRI-O has a vulnerability in environment-variable handling during container creation. When a CreateContainer request has a nil Envs field, CRI-O uses unfiltered config.Env entries from the OCI image, which can cause a Go panic and crash the crio daemon. This occurs when an entry lacks '='.

A flaw was found in CRI-O where the fix for a previous vulnerability (CVE-2022-4318) was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME variable, enabling arbitrary lines to be added to /etc/passwd.

There's a vulnerability in the CRI-O application where when a container is launched with securityContext.runAsUser specifying a non-existent user, CRI-O attempts to create the user, reading the container's entire /etc/passwd file into memory. If this file is excessively large, it can cause high memory consumption leading applications to be killed due to out-of-memory. As a result a denial-of-service can be achieved, possibly disrupting other pods and services running on the same host.

A vulnerability was found in CRI-O. A path traversal issue in the log management functions (UnMountPodLogs and LinkContainerLogs) may allow an attacker with permissions to create and delete Pods to unmount arbitrary host paths, leading to node-level denial of service by unmounting critical system directories.

A flaw was found in cri-o. A malicious container can create a symbolic link to arbitrary files on the host via directory traversal (“../“). This flaw allows the container to read and write to arbitrary files on the host system.
