{"id":"AZL-106071","summary":"CVE-2026-98217 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nIB/mlx4: Fix use-after-free on pkey sysfs registration failure\n\nregister_pkey_tree() ignores errors from register_one_pkey_tree() and\ncontinues registering the remaining slaves. The per-slave error path has\nalready released the pkey parent kobjects, but their pointers remain\nstored in the device. A later device cleanup therefore passes the stale\npointers to kobject_put(), causing a use-after-free.\n\nClear the parent pointers after releasing a failed slave tree and skip\nunregistered trees during device cleanup. This preserves the existing\nbest-effort registration behavior while preventing a second cleanup of\nthe failed tree.","modified":"2026-10-07T14:16:56.672245576Z","published":"2026-10-06T09:18:08Z","upstream":["CVE-2026-98217"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98217"}],"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-106071.json"}}],"schema_version":"1.9.0"}
