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-2025-40294 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2025-40294/ (Markdown: https://insights.sbomify.com/CVE-2025-40294/index.md)","id":"CVE-2025-40294","markdown":"https://insights.sbomify.com/CVE-2025-40294/index.md","name":"CVE-2025-40294","record":{"aliases":["BELL-CVE-2025-40294","DEBIAN-CVE-2025-40294","GHSA-23g6-rffg-7f3p","ROOT-OS-DEBIAN-12-CVE-2025-40294","ROOT-OS-DEBIAN-13-CVE-2025-40294","ROOT-OS-UBUNTU-2404-CVE-2025-40294","UBUNTU-CVE-2025-40294"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth","requires_auth":"low_privilege","summary":"A local attacker with low privileges can trigger an out-of-bounds write in the Linux kernel Bluetooth subsystem, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: MGMT: Fix OOB access in parse_adv_monitor_pattern()\n\nIn the parse_adv_monitor_pattern() function, the value of\nthe 'length' variable is currently limited to HCI_MAX_EXT_AD_LENGTH(251).\nThe size of the 'value' array in the mgmt_adv_pattern structure is 31.\nIf the value of 'pattern[i].length' is set in the user space\nand exceeds 31, the 'patterns[i].value' array can be accessed\nout of bound when copied.\n\nIncreasing the size of the 'value' array in\nthe 'mgmt_adv_pattern' structure will break the userspace.\nConsidering this, and to avoid OOB access revert the limits for 'offset'\nand 'length' back to the value of HCI_MAX_AD_LENGTH.\n\nFound by InfoTeCS on behalf of Linux Verification Center\n(linuxtesting.org) with SVACE.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Bluetooth: MGMT: Fix OOB access in parse_adv_monitor_pattern()","id":"CVE-2025-40294","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"fscrypt: fix left shift underflow when inode-\u003ei_blkbits \u003e PAGE_SHIFT","id":"CVE-2025-40295"},"packages":[],"prev":{"headline":"iommufd: Don't overflow during division for dirty tracking","id":"CVE-2025-40293"},"products":["Linux"],"published":"2025-12-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-16","vendors":["Linux"]},"summary":"A local attacker with low privileges can trigger an out-of-bounds write in the Linux kernel Bluetooth subsystem, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2025-40294/"}
