Descripción técnica

In the Linux kernel, the following vulnerability has been resolved: vxlan: require CAP_NET_ADMIN in the device netns for changelink A tunnel changelink() operates on at most two netns, dev_net(dev) and the sticky underlay netns vxlan->net. They differ once the device is created in or moved to a netns other than the one the request runs in. The rtnl changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a caller privileged there but not in vxlan->net can rewrite a vxlan device whose underlay lives in vxlan->net. vxlan_changelink() validates and applies the new configuration against vxlan->net (vxlan_config_validate(vxlan->net, ...)) and can reopen the underlay socket in that netns, so the same reasoning as the tunnel changelink series applies here. Gate vxlan_changelink() with rtnl_dev_link_net_capable(), at the top of the op before any attribute is parsed, matching ipgre_changelink() and the rest of the "require CAP_NET_ADMIN in the device netns for changelink" series.

———Incorrect authorization in the issuer resolution logic in AWS Private CA Connector for Kubernetes (aws-privateca-issuer) before v1.10.1 might allow an authenticated remote user to obtain certificates, including subordinate CA certificates, signed by a cluster-scoped AWS Private CA issuer that their approval policy does not authorize. To remediate this issue, users should upgrade aws-privateca-issuer to version v1.10.1 or the AWS Private CA Connector for Kubernetes EKS add-on to version v1.10.1-eksbuild.1, and update any certificate requests, Certificate resources, or Ingress annotations whose issuerRef.kind is missing, incorrect, or does not match the referenced issuer, since v1.10.1 requires issuerRef.kind to be exactly AWSPCAIssuer or AWSPCAClusterIssuer and to match the issuer it references.2h CVE-2026-853304.3 MED

——0OAuthLib is an implementation of the OAuth request-signing logic for Python 3.6+. Prior to 4.0.0, the client_credentials and Resource Owner Password Credentials token grant handlers can authenticate request.client as one confidential client while retaining an attacker-supplied request.client_id for validate_grant_type and validate_scopes. A lower-privilege authenticated client can therefore cause grant and scope authorization to use another client's identity when an application validator relies on the documented client_id argument, potentially issuing tokens with unauthorized grants or scopes. Validators that authorize exclusively from request.client may not be affected. This issue is fixed in version 4.0.0.3h CVE-2026-118668—

——0langgraph-api implements the LangGraph API for rapid development and testing. From 0.1.2 until 0.15.0, JavaScript or TypeScript custom authentication Store authorization handlers can return a rewritten namespace that is not carried across the runtime boundary and applied before the Store operation. An authenticated user can therefore access another user's Store namespace when a deployment relies on namespace rewriting for isolation, allowing unauthorized reads, overwrites, searches, or deletions. Python custom authentication and handlers that reject unauthorized namespaces instead of rewriting them are not affected. This issue is fixed in version 0.15.0.22h
