{"id":"CVE-2025-71071","summary":"iommu/mediatek: fix use-after-free on probe deferral","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niommu/mediatek: fix use-after-free on probe deferral\n\nThe driver is dropping the references taken to the larb devices during\nprobe after successful lookup as well as on errors. This can\npotentially lead to a use-after-free in case a larb device has not yet\nbeen bound to its driver so that the iommu driver probe defers.\n\nFix this by keeping the references as expected while the iommu driver is\nbound.","modified":"2026-04-16T04:33:01.003031356Z","published":"2026-01-13T15:31:25.400Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71071.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1ef70a0b104ae8011811f60bcfaa55ff49385171"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5c04217d06a1161aaf36267e9d971ab6f847d5a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/896ec55da3b90bdb9fc04fedc17ad8c359b2eee5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de83d4617f9fe059623e97acf7e1e10d209625b5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6c08d3aa441bbc1956e9d65f1cbb89113a5aa8a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71071.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71071"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"8412e5dd24ffc8bc21a00bfaa0b80d4596cdc9da"},{"fixed":"896ec55da3b90bdb9fc04fedc17ad8c359b2eee5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"26593928564cf5b576ff05d3cbd958f57c9534bb"},{"fixed":"5c04217d06a1161aaf36267e9d971ab6f847d5a7"},{"fixed":"1ef70a0b104ae8011811f60bcfaa55ff49385171"},{"fixed":"f6c08d3aa441bbc1956e9d65f1cbb89113a5aa8a"},{"fixed":"de83d4617f9fe059623e97acf7e1e10d209625b5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"51080de72e26771f0ed9d44982974279ccbc92b8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71071.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.120"},{"fixed":"6.12.64"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.18.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71071.json"}}],"schema_version":"1.7.5"}
