{"id":"AZL-101927","summary":"CVE-2026-90341 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: coreboot: Validate table bounds\n\nThe existing coreboot_table_populate() bounds checks limit individual\nentries to the mapped length.  However, coreboot_table_probe() replaces\nthe platform resource length with header and table sizes supplied by\nfirmware before mapping the full table.\n\nA malformed table can overflow the 32-bit size addition or advertise an\nextent beyond the resource, causing the driver to map and parse memory\noutside the resource.  A resource shorter than the fixed header is also\nmapped as though it contained a complete header.\n\nReject resources shorter than the fixed header.  After validating the\nsignature, require a complete header, calculate the advertised extent\nwith overflow checking, and reject extents beyond the resource before\nremapping the table.","modified":"2026-09-18T14:15:21.420174420Z","published":"2026-09-17T17:17:32Z","upstream":["CVE-2026-90341"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90341"}],"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-101927.json"}}],"schema_version":"1.9.0"}
