{"id":"AZL-100817","summary":"CVE-2026-89452 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niommu/msm: Unwind probe state on registration failure\n\nmsm_iommu_probe() adds its devm-managed IOMMU object to\nqcom_iommu_devices before adding the IOMMU sysfs device and registering\nit with the IOMMU core.\n\nIf iommu_device_sysfs_add() fails, probe returns with the object still on\nqcom_iommu_devices. The driver core then releases the devm allocation,\nleaving a dangling list entry that later list walks may dereference.\n\nIf iommu_device_register() fails, the same dangling list entry remains\nand the sysfs device is left registered as well.\n\nUnwind the sysfs device and global list entry in reverse setup order on\nthe corresponding failure paths.","modified":"2026-09-12T14:15:16.263558136Z","published":"2026-09-11T20:19:25Z","upstream":["CVE-2026-89452"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89452"}],"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-100817.json"}}],"schema_version":"1.9.0"}
