{"id":"AZL-96362","summary":"CVE-2026-72098 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndm-verity: fix buffer overflow in FEC calculation\n\nThere's a buffer overflow in dm-verity-fec:\n\nif (neras && *neras \u003c= v-\u003efec-\u003eroots)\n\tfio-\u003eerasures[(*neras)++] = i;\n\nThis allows *neras to reach roots + 1 (the post-increment pushes it past\nroots). This value is then passed as no_eras to decode_rs8(). Inside the\nRS decoder (lib/reed_solomon/decode_rs.c:113-121), the erasure locator\npolynomial loop writes lambda[j] where j can reach nroots + 1 — one\nelement past the end of lambda[] (which is sized nroots + 1, valid\nindices 0..nroots). The out-of-bounds write lands on syn[0], corrupting\nthe syndrome buffer.","modified":"2026-08-30T05:26:50Z","published":"2026-08-15T06:21:23Z","upstream":["CVE-2026-72098"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72098"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96362.json"}}],"schema_version":"1.9.0"}
