{"id":"AZL-57498","summary":"CVE-2024-45779 affecting package grub2 for versions less than 2.06-25","details":"An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a heap of bounds read. As a consequence, sensitive data may be leaked, or grub2 will crash.","modified":"2026-04-01T05:19:09.375392Z","published":"2025-03-03T15:15:14Z","upstream":["CVE-2024-45779"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-45779"}],"affected":[{"package":{"name":"grub2","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/grub2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.06-25"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-57498.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:H"}]}
