An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-28390 in the wild and no public exploit code.\n\nAffected product: Openssl Openssl. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-28390/ (Markdown: https://insights.sbomify.com/CVE-2026-28390/index.md)","id":"CVE-2026-28390","markdown":"https://insights.sbomify.com/CVE-2026-28390/index.md","name":"CVE-2026-28390","record":{"aliases":["ALPINE-CVE-2026-28390","ALSA-2026:22313","ALSA-2026:22314","ALSA-2026:22315","ALSA-2026:38503","AZL-82070","AZL-82106","AZL-82208","BELL-CVE-2026-28390","CLSA-2026-1777393624","CLSA-2026-1777397374","CLSA-2026-1777541792","CLSA-2026-1777566580","CLSA-2026-1777567181","CLSA-2026-1777567430","CLSA-2026-1780710220","CLSA-2026-1781165688","DEBIAN-CVE-2026-28390","ECHO-9d88-691e-4e0f","GHSA-fgpp-q3px-3xhc","JLSEC-2026-275","MINI-hrr9-5jqm-32g4","MINI-jrq2-58qh-q9v2","MINI-jw43-5hx9-wwv3","RHSA-2026:14217","RHSA-2026:22313","RHSA-2026:22314","RHSA-2026:22315","RHSA-2026:38503","RHSA-2026:38804","RHSA-2026:38805","RHSA-2026:43513","RHSA-2026:44480","RHSA-2026:47096","RLSA-2026:22312","RLSA-2026:22313","RLSA-2026:22314","RLSA-2026:22315","RLSA-2026:38503","ROOT-OS-ALPINE-315-CVE-2026-28390","ROOT-OS-ALPINE-317-CVE-2026-28390","SUSE-SU-2026:1429-1","SUSE-SU-2026:1549-1","SUSE-SU-2026:1550-1","SUSE-SU-2026:1562-1","SUSE-SU-2026:1605-1","SUSE-SU-2026:1711-1","SUSE-SU-2026:21244-1","SUSE-SU-2026:3272-1","SUSE-SU-2026:3443-1","UBUNTU-CVE-2026-28390"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSL cryptographic library","requires_auth":"none","summary":"Attackers can cause a denial of service by sending crafted CMS data that triggers a NULL pointer dereference in OpenSSL.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Issue summary: During processing of a crafted CMS EnvelopedData message\nwith KeyTransportRecipientInfo a NULL pointer dereference can happen.\n\nImpact summary: Applications that process attacker-controlled CMS data may\ncrash before authentication or cryptographic operations occur resulting in\nDenial of Service.\n\nWhen a CMS EnvelopedData message that uses KeyTransportRecipientInfo with\nRSA-OAEP encryption is processed, the optional parameters field of\nRSA-OAEP SourceFunc algorithm identifier is examined without checking\nfor its presence.
