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-2026-97446 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-2026-97446/ (Markdown: https://insights.sbomify.com/CVE-2026-97446/index.md)","id":"CVE-2026-97446","markdown":"https://insights.sbomify.com/CVE-2026-97446/index.md","name":"CVE-2026-97446","record":{"aliases":["AZL-103985","BELL-CVE-2026-97446","DEBIAN-CVE-2026-97446","GHSA-hqv9-j885-c7xr","UBUNTU-CVE-2026-97446"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A NULL pointer dereference in the Linux kernel's ACPICA component allows a local attacker to cause a system crash via malicious firmware.","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\nACPICA: Fix NULL pointer dereference in acpi_ns_custom_package()\n\nacpi_ns_custom_package() unconditionally dereferences the first element\nof the package to read the _BIX version number, without checking for\nNULL:\n\n    if ((*Elements)-\u003eCommon.Type != ACPI_TYPE_INTEGER)\n\nWhen firmware returns a _BIX package whose first element is an\nunresolvable reference, ACPICA evaluates that entry to NULL.\nacpi_ns_remove_null_elements() does not strip NULL entries for\nACPI_PTYPE_CUSTOM packages (fixed-position format would break if\nelements were shifted), so acpi_ns_custom_package() sees the NULL\nand causes a crash.\n\nAdd a NULL check for the first element (version field) before\ndereferencing it.
