{"apiVersion":"1.0","identifier":"CVE-2026-72098","description":"In the Linux kernel, the following vulnerability has been resolved: dm-verity: fix buffer overflow in FEC calculation There-s a buffer overflow in dm-verity-fec: if (neras && *neras <= v->fec->roots) fio->erasures[(*neras)++] = i; This allows *neras to reach roots + 1 (the post-increment pushes it past roots). This value is then passed as no_eras to decode_rs8(). Inside the RS decoder (lib/reed_solomon/decode_rs.c:113-121), the erasure locator polynomial loop writes lambda[j] where j can reach nroots + 1 — one element past the end of lambda[] (which is sized nroots + 1, valid indices 0..nroots). The out-of-bounds write lands on syn[0], corrupting the syndrome buffer.","publishedAt":"2026-08-15T06:21:23","lastModifiedAt":"2026-08-17T06:18:08","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72098","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00646,"riskScore":1.04,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72098","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72098","en":"https://www.redsauce.net/en/cves/CVE-2026-72098","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72098","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72098","de":"https://www.redsauce.net/de/cves/CVE-2026-72098","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72098","el":"https://www.redsauce.net/el/cves/CVE-2026-72098"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72098"}}
