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-2026-45258 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-2026-45258/ (Markdown: https://insights.sbomify.com/CVE-2026-45258/index.md)","id":"CVE-2026-45258","markdown":"https://insights.sbomify.com/CVE-2026-45258/index.md","name":"CVE-2026-45258","record":{"aliases":[],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"FreeBSD kernel","requires_auth":"low_privilege","summary":"Integer overflow in FreeBSD sound driver allows local users to read/write kernel memory, leading to privilege escalation or system crash.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[{"product":"freebsd","vendor":"freebsd"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-681","name":"Incorrect Conversion between Numeric Types"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"dsp_mmap_single() validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size.  This addition could overflow, so that a large offset and length wrapped around and passed the check.  The offset was then narrowed from 64 to 32 bits when converted to a buffer address, yielding a mapping that extended past the audio buffer into unrelated kernel memory.\n\nThe /dev/dsp device nodes are world-accessible by default.  On a system with an audio device, either issue allows an unprivileged local user to read and write kernel memory, which can be used to escalate privileges, potentially gaining full control of the affected system.  At a minimum, an attacker can crash the kernel, resulting in a Denial of Service (DoS).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-10","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-10T02:44:04Z","kind":"github_poc","ref":"https://github.com/Yayoi-cs/CVE-2026-45258_1day_LPE_exploit","stars":0,"title":"1-day exploit for CVE-2026-45258"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Multiple vulnerabilities in the sound(4) mmap path","id":"CVE-2026-45258","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freebsd:freebsd","products":["freebsd:freebsd"],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"sigqueue(2) missing capability mode restriction","id":"CVE-2026-45259"},"packages":[],"prev":{"headline":"Arbitrary file overwrite via the KTLS receive path","id":"CVE-2026-45257"},"products":["FreeBSD"],"published":"2026-06-27","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-30","vendors":["FreeBSD"]},"summary":"Integer overflow in FreeBSD sound driver allows local users to read/write kernel memory, leading to privilege escalation or system crash.","url":"https://insights.sbomify.com/CVE-2026-45258/"}
