一、漏洞信息
漏洞编号：CVE-2026-74291
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.12.33,6.18.18,6.4.0,6.6.0
CVSS评分：
BaseScore：N/A None
Vector：
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:ASoC: topology: Check PCM and DAI name strings before useTopology objects store several PCM and DAI names in fixed-size UAPIarrays. Other topology parser paths validate these fields with boundedstrnlen() checks before using them as C strings, but the PCM and DAIpaths still pass some fixed-size arrays directly to strlen(),devm_kstrdup(), DAI lookup, and diagnostic prints.A malformed topology blob with a non-NUL-terminated PCM, DAI, or streamcapability name can therefore make the parser read past the end of thefixed-size field.Reject unterminated PCM and DAI name fields before consuming them as Cstrings.
