Therefore, sg_dma_len() is invalid\nand could return zero or a stale DMA length, causing encryption and\ndecryption to process the wrong number of bytes when\nCONFIG_NEED_SG_DMA_LENGTH=y.\n\nUse the original scatterlist length instead.","modified":"2026-09-05T14:16:56.871253208Z","published":"2026-09-04T16:18:11Z","upstream":["CVE-2026-80831"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80831"}],"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-99402.json"}}],"schema_version":"1.9.0"}
