{"id":"AZL-87137","summary":"CVE-2025-68251 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nerofs: avoid infinite loops due to corrupted subpage compact indexes\n\nRobert reported an infinite loop observed by two crafted images.\n\nThe root cause is that `clusterofs` can be larger than `lclustersize`\nfor !NONHEAD `lclusters` in corrupted subpage compact indexes, e.g.:\n\n  blocksize = lclustersize = 512   lcn = 6   clusterofs = 515\n\nMove the corresponding check for full compress indexes to\n`z_erofs_load_lcluster_from_disk()` to also cover subpage compact\ncompress indexes.\n\nIt also fixes the position of `m-\u003etype \u003e= Z_EROFS_LCLUSTER_TYPE_MAX`\ncheck, since it should be placed right after\n`z_erofs_load_{compact,full}_lcluster()`.","modified":"2026-08-29T05:27:27Z","published":"2025-12-16T15:15:54Z","upstream":["CVE-2025-68251"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68251"}],"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-87137.json"}}],"schema_version":"1.9.0"}
