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-2024-46793 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-46793/ (Markdown: https://insights.sbomify.com/CVE-2024-46793/index.md)","id":"CVE-2024-46793","markdown":"https://insights.sbomify.com/CVE-2024-46793/index.md","name":"CVE-2024-46793","record":{"aliases":["BELL-CVE-2024-46793","DEBIAN-CVE-2024-46793","GHSA-47fg-g734-5wff","UBUNTU-CVE-2024-46793"],"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":"low_privilege","summary":"A NULL pointer dereference in Intel ASoC board drivers can cause a kernel crash, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: Intel: Boards: Fix NULL pointer deref in BYT/CHT boards harder\n\nSince commit 13f58267cda3 (\"ASoC: soc.h: don't create dummy Component\nvia COMP_DUMMY()\") dummy codecs declared like this:\n\nSND_SOC_DAILINK_DEF(dummy,\n        DAILINK_COMP_ARRAY(COMP_DUMMY()));\n\nexpand to:\n\nstatic struct snd_soc_dai_link_component dummy[] = {\n};\n\nWhich means that dummy is a zero sized array and thus dais[i].codecs should\nnot be dereferenced *at all* since it points to the address of the next\nvariable stored in the data section as the \"dummy\" variable has an address\nbut no size, so even dereferencing dais[0] is already an out of bounds\narray reference.\n\nWhich means that the if (dais[i].codecs-\u003ename) check added in\ncommit 7d99a70b6595 (\"ASoC: Intel: Boards: Fix NULL pointer deref\nin BYT/CHT boards\") relies on that the part of the next variable which\nthe name member maps to just happens to be NULL.\n\nWhich apparently so far it usually is, except when it isn't\nand then it results in crashes like this one:\n\n[   28.795659] BUG: unable to handle page fault for address: 0000000000030011\n...\n[   28.795780] Call Trace:\n[   28.795787]  \u003cTASK\u003e\n...\n[   28.795862]  ?
