{"id":"AZL-109002","summary":"CVE-2026-98855 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nof/overlay: put property on deadprops only after changeset add succeeds\n\nadd_changeset_property() links a new property of a not-yet-live\ntarget node into the node's deadprops list before handing it to\nof_changeset_add_property(). If that fails, the error path frees the\nproperty but leaves the freed pointer linked in deadprops, and\nof_node_release() frees it a second time when the aborted overlay's\nnode is released.\n\nRecord the changeset entry first and link the property into deadprops\nonly on success. of_changeset_add_property() never looks at the\nnode's property lists, so the order of the two steps is otherwise\nimmaterial, and the error path frees a property that nothing\nreferences.","modified":"2026-10-19T14:16:50.075503921Z","published":"2026-10-18T16:17:39Z","upstream":["CVE-2026-98855"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98855"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-109002.json"}}],"schema_version":"1.9.0"}
