It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-23087 in the wild and no public exploit code.\n\nAffected product: Freebsd Freebsd. 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-2022-23087/ (Markdown: https://insights.sbomify.com/CVE-2022-23087/index.md)","id":"CVE-2022-23087","markdown":"https://insights.sbomify.com/CVE-2022-23087/index.md","name":"CVE-2022-23087","record":{"aliases":["GHSA-rmqc-8468-5wx2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"FreeBSD bhyve hypervisor","requires_auth":"low_privilege","summary":"A guest VM can trigger an out-of-bounds write in the bhyve e1000 emulation, potentially allowing host code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[{"product":"freebsd","vendor":"freebsd"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted.  These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload (\"TSO\").  The e1000 device model uses an on-stack buffer to generate the modified packet header when simulating these modifications on transmitted packets.\n\nWhen checksum offload is requested for a transmitted packet, the e1000 device model used a guest-provided value to specify the checksum offset in the on-stack buffer.  The offset was not validated for certain packet types.\n\nA misbehaving bhyve guest could overwrite memory in the bhyve process on the host, possibly leading to code execution in the host context.\n\nThe bhyve process runs in a Capsicum sandbox, which (depending on the FreeBSD version and bhyve configuration) limits the impact of exploiting this issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Bhyve e82545 device emulation out-of-bounds write","id":"CVE-2022-23087","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freebsd:freebsd","products":["freebsd:freebsd"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"802.11 heap buffer overflow","id":"CVE-2022-23088"},"packages":[],"prev":{"headline":"mpr/mps/mpt driver ioctl heap out-of-bounds write","id":"CVE-2022-23086"},"products":["FreeBSD"],"published":"2024-02-15","related":[{"cvss_score":10,"headline":"Memory corruption in FreeBSD","id":"CVE-2018-17160","kev_date_added":null,"published":"2018-12-04"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-3954","kev_date_added":null,"published":"2014-10-27"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2006-4304","kev_date_added":null,"published":"2006-08-24"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2006-0226","kev_date_added":null,"published":"2006-01-19"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2004-0002","kev_date_added":null,"published":"2004-02-03"},{"cvss_score":10,"headline":"Security feature bypass in n/a","id":"CVE-2001-0969","kev_date_added":null,"published":"2002-03-09"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2001-0388","kev_date_added":null,"published":"2001-09-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-27","vendors":["FreeBSD"]},"summary":"A guest VM can trigger an out-of-bounds write in the bhyve e1000 emulation, potentially allowing host code execution.","url":"https://insights.sbomify.com/CVE-2022-23087/"}
