{"apiVersion":"1.0","identifier":"CVE-2026-72304","description":"In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-control: Fix TOCTOU in sof_ipc4_bytes_put In sof_ipc4_bytes_put(), the copy size is derived from the old data->size in the buffer rather than the incoming new data-s size field from ucontrol. If the new data has a different size, the copy uses the wrong length: it may truncate valid data or copy stale bytes. Fix by validating and using the incoming data-s sof_abi_hdr.size from ucontrol before copying.","publishedAt":"2026-08-15T06:22:03","lastModifiedAt":"2026-08-17T06:18:33","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72304","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00163,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72304","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72304","en":"https://www.redsauce.net/en/cves/CVE-2026-72304","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72304","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72304","de":"https://www.redsauce.net/de/cves/CVE-2026-72304","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72304","el":"https://www.redsauce.net/el/cves/CVE-2026-72304"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72304"}}
