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-2026-22796 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-2026-22796/ (Markdown: https://insights.sbomify.com/CVE-2026-22796/index.md)","id":"CVE-2026-22796","markdown":"https://insights.sbomify.com/CVE-2026-22796/index.md","name":"CVE-2026-22796","record":{"aliases":["ALPINE-CVE-2026-22796","AZL-75299","AZL-75348","AZL-75905","AZL-76110","AZL-76161","AZL-78579","BELL-CVE-2026-22796","CLEANSTART-2026-PQ44811","CLSA-2026-1770136337","DEBIAN-CVE-2026-22796","ECHO-f3f1-7685-1435","GHSA-r9hf-rxjm-gv2f","JLSEC-2026-270","MINI-5m6m-jch6-rhcc","MINI-g3rp-9rg4-vjcv","MINI-vq8c-vrvw-h2g8","UBUNTU-CVE-2026-22796"],"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":"An attacker can cause a denial of service in applications verifying PKCS#7 signatures by providing malformed data that triggers a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"Issue summary: A type confusion vulnerability exists in the signature\nverification of signed PKCS#7 data where an ASN1_TYPE union member is\naccessed without first validating the type, causing an invalid or NULL\npointer dereference when processing malformed PKCS#7 data.\n\nImpact summary: An application performing signature verification of PKCS#7\ndata or calling directly the PKCS7_digest_from_attributes() function can be\ncaused to dereference an invalid or NULL pointer when reading, resulting in\na Denial of Service.\n\nThe function PKCS7_digest_from_attributes() accesses the message digest attribute\nvalue without validating its type.
