CWE-244 vulnerabilities

IBM Concert versions 1.0.0 through 3.0.0 contain a vulnerability classified as CWE-244 (Heap Inspection) that allows information disclosure via heap inspection. This vulnerability has a CVSS 3.1 base score of 4.7, indicating a medium severity level. The flaw requires local access with low privileges and high attack complexity, and it does not require user interaction. The vulnerability impacts confidentiality but does not affect integrity or availability.

nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.7, internal/pki/resolver.go:36-64 constructs a CAManager with the plaintext ed25519.PrivateKey after unwrapping via the master key; internal/pki/ca.go:13-16 stores it. Callers at internal/api/enroll.go:116, internal/api/updates.go:297, and internal/api/mobile_bundle.go:40 use the manager for one Sign() and drop the reference on function return — but the underlying slice contents are not wiped before release. The keystore package's contract (internal/keystore/keystore.go doc: "Callers MUST zeroise the returned plaintext DEK as soon as it is no longer needed") is not met by the CAManager consumer. Decrypted CA private keys persist in process heap until Go's GC scavenges the underlying slice — minutes to hours under load, indefinitely on idle servers. This issue has been patched in version 0.3.7.

IBM Concert 1.0.0 through 2.1.0 could allow an attacker to obtain sensitive information using man in the middle techniques due to improper clearing of heap memory.

IBM Concert 1.0.0 through 2.1.0 could allow a remote attacker to obtain sensitive information from allocated memory due to improper clearing of heap memory.

IBM Concert 1.0.0 through 2.1.0 could allow a remote attacker to obtain sensitive information from allocated memory due to improper clearing of heap memory.

IBM Concert 1.0.0 through 2.1.0 could allow a remote attacker to obtain sensitive information from allocated memory due to improper clearing of heap memory.

CVE-2025-36118 is a high-severity vulnerability affecting IBM Storage Virtualize versions 8.4, 8.5, 8.7, and 9.1. It stems from improper clearing of heap memory before release in the IKEv1 implementation, allowing remote attackers to retrieve sensitive information from device memory during Security Association negotiation requests. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network. While it does not impact integrity or availability, the confidentiality breach could expose critical data. No known exploits are currently in the wild, but the vulnerability's nature and IBM Storage Virtualize's deployment in enterprise environments make it a significant risk. European organizations using these IBM storage solutions should prioritize patching once available and implement network-level protections to mitigate exposure.

IBM Concert Software 1.0.0 through 2.0.0 could allow a local user to obtain sensitive information from buffers due to improper clearing of heap memory before release.

IBM Concert Software 1.0.0 through 1.1.0 could allow a remote attacker to obtain sensitive information from allocated memory due to improper clearing of heap memory.

IBM MQ Operator LTS 2.0.0 through 2.0.29, MQ Operator CD 3.0.0, 3.0.1, 3.1.0 through 3.1.3, 3.3.0, 3.4.0, 3.4.1, 3.5.0, 3.5.1, 3.6.0, and MQ Operator SC2 3.2.0 through 3.2.13 Container could disclose sensitive information to a local user due to improper clearing of heap memory before release.
