{"id":"AZL-100439","summary":"CVE-2026-89730 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfpga: altera-cvp: Avoid out-of-bounds read in trailing byte write\n\nThe trailing byte path in altera_cvp_send_block() dereferences a u32\npointer even when only 1-3 bytes remain in the input buffer. If the buffer\nends at a page or scatterlist boundary, this can read past the valid image\ndata and fault.\n\nCopy the remaining bytes into a zero-initialized u32 before writing the\nfinal word so only valid bytes are read from the input buffer.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:20:03Z","upstream":["CVE-2026-89730"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89730"}],"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-100439.json"}}],"schema_version":"1.9.0"}
