{"apiVersion":"1.0","identifier":"CVE-2026-72301","description":"In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc3-control: Fix TOCTOU in bytes_put and bytes_get In sof_ipc3_bytes_put(), the size used for the memcpy is derived from the old data->size already in the buffer, not the incoming new data-s size field. If the new data has a different size, the copy length is wrong: it may truncate valid data or copy stale bytes. Similarly, sof_ipc3_bytes_get() checks data->size against max_size without accounting for the sizeof(struct sof_ipc_ctrl_data) offset of the flex array within the allocation. Fix bytes_put to validate and use the incoming data-s sof_abi_hdr.size from ucontrol before copying. Fix bytes_get to subtract sizeof(*cdata) from the bounds check to match the actual available space.","publishedAt":"2026-08-15T06:22:02","lastModifiedAt":"2026-08-17T06:18:33","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72301","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00164,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72301","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72301","en":"https://www.redsauce.net/en/cves/CVE-2026-72301","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72301","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72301","de":"https://www.redsauce.net/de/cves/CVE-2026-72301","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72301","el":"https://www.redsauce.net/el/cves/CVE-2026-72301"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72301"}}
