{"id":"AZL-102600","summary":"CVE-2026-90283 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nhugetlbfs: release subpool on fill_super failure\n\nhugetlbfs_fill_super() allocates a hugepage subpool when size or min_size\nmount options are specified.  hugepage_new_subpool() may also reserve huge\npages for min_size.\n\nIf root dentry creation fails after the subpool is created, the failure\npath frees the subpool with kfree().  This bypasses hugepage_put_subpool()\nand can leave min_size reservations charged.\n\nUse hugepage_put_subpool() on the failure path, matching the normal\nput_super path.","modified":"2026-09-19T05:33:49Z","published":"2026-09-17T17:17:25Z","upstream":["CVE-2026-90283"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90283"}],"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-102600.json"}}],"schema_version":"1.9.0"}
