CVE-2026-62146

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 vulnerability in CRI-O checkpoint restore allows a user who can create a pod from a malicious checkpointed container to bypass the destination Kubernetes security context. The restored process may retain credentials, Linux capabilities, no_new_privs, and seccomp state from the checkpoint instead of enforcing the destination configuration.

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 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.
