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-2026-93115 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-2026-93115/ (Markdown: https://insights.sbomify.com/CVE-2026-93115/index.md)","id":"CVE-2026-93115","markdown":"https://insights.sbomify.com/CVE-2026-93115/index.md","name":"CVE-2026-93115","record":{"aliases":["AZL-102006","BELL-CVE-2026-93115","DEBIAN-CVE-2026-93115","GHSA-hf49-hh29-x2wv","UBUNTU-CVE-2026-93115"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"high_privilege","summary":"A local attacker with high privileges can force-bind a driver to a device lacking an ACPI companion, causing a kernel NULL pointer dereference and system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nplatform/mellanox: mlxbf-pmc: Check ACPI_COMPANION() against NULL\n\nEvery platform driver can be forced to match a device that doesn't match\nits list of device IDs because of device_match_driver_override(), so\nplatform drivers that rely on the existence of a device's ACPI companion\nobject need to verify its presence.\n\nmlxbf_pmc_probe() passes the result of ACPI_COMPANION() to\nacpi_device_hid(), which dereferences it, so force-binding the driver to\na device without an ACPI companion leads to a NULL pointer dereference.\n\nAccordingly, add a requisite ACPI_COMPANION() check against NULL to the\nmlxbf-pmc driver and return -ENODEV when the companion is missing.","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":"platform/mellanox: mlxbf-pmc: Check ACPI_COMPANION() against NULL","id":"CVE-2026-93115","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"platform/x86: asus-wmi: fix resource leaks on probe failure","id":"CVE-2026-93116"},"packages":[],"prev":{"headline":"platform/surface: acpi-notify: Check ACPI companion before use","id":"CVE-2026-93114"},"products":["Linux"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A local attacker with high privileges can force-bind a driver to a device lacking an ACPI companion, causing a kernel NULL pointer dereference and system crash.","url":"https://insights.sbomify.com/CVE-2026-93115/"}
