This worked\nby accident as the remaining COMP_EMPTY() platform entry became the codec\nentry, and the platform entry became completely empty, effectively the\nsame as COMP_DUMMY() since snd_soc_fill_dummy_dai() doesn't do anything\nfor platform entries.\n\nThis causes a KASAN out-of-bounds warning in mtk_soundcard_common_probe()\nin sound/soc/mediatek/common/mtk-soundcard-driver.c:\n\n\tfor_each_card_prelinks(card, i, dai_link) {\n\t\tif (adsp_node && !strncmp(dai_link->name, \"AFE_SOF\", strlen(\"AFE_SOF\")))\n\t\t\tdai_link->platforms->of_node = adsp_node;\n\t\telse if (!dai_link->platforms->name && !dai_link->platforms->of_node)\n\t\t\tdai_link->platforms->of_node = platform_node;\n\t}\n\nwhere the code expects the platforms array to have space for at least one entry.\n\nAdd an COMP_EMPTY() entry so that dai_link->platforms has space.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-129"],"references":["https://git.kernel.org/stable/c/282a4482e198e03781c152c88aac8aa382ef9a55","https://git.kernel.org/stable/c/42b9ab7a4d7e6c5efd71847541e4fcc213585aad","https://git.kernel.org/stable/c/62f61129621ce7e05a6d24584660f79bf081b483","https://git.kernel.org/stable/c/282a4482e198e03781c152c88aac8aa382ef9a55","https://git.kernel.org/stable/c/42b9ab7a4d7e6c5efd71847541e4fcc213585aad"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:53:51.317825789+00:00"},"epss":{"cve":"CVE-2024-42088","score":0.00236,"percentile":0.14654,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
