{"id":"CVE-2026-72245","summary":"gpu: host1x: Fix device reference leak in host1x_device_parse_dt() error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpu: host1x: Fix device reference leak in host1x_device_parse_dt() error path\n\nAfter device_initialize(), the embedded struct device in struct\nhost1x_device should be released through the device core with\nput_device().\n\nIn host1x_device_add(), if host1x_device_parse_dt() fails, the current\nerror path frees the object directly with kfree(device). That bypasses\nthe normal device lifetime handling and leaks the reference held on the\nembedded struct device.\n\nThe issue was identified by a static analysis tool I developed and\nconfirmed by manual review.\n\nFix this by using put_device() in the host1x_device_parse_dt() failure\npath.","modified":"2026-08-18T03:31:07.965200686Z","published":"2026-08-15T05:54:32.611Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72245.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3642d0a45214e3b4cf61bf5e75b04b490d0b3519"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4454caa204a2edb19c62754ddb96e5dbca0d2f49"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4ee41361c637eafa80f5d88b46d0016e6cdb24db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8559b1501f77a5b5d003790bec170ca449e0c674"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a408d89e20d38d78f540e1951dc4c6056ad662e1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c4d6442ac3ed00041fe4e1df715717ed78a7d37f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e75717f9aec04355777be41070890c6a815c76df"},{"type":"WEB","url":"https://git.kernel.org/stable/c/edc7267b59a465c6ae7c5ffac2171c30962bd325"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72245.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72245"},{"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":"f4c5cf88fbd50e4779042268947b2e2f90c20484"},{"fixed":"a408d89e20d38d78f540e1951dc4c6056ad662e1"},{"fixed":"4ee41361c637eafa80f5d88b46d0016e6cdb24db"},{"fixed":"3642d0a45214e3b4cf61bf5e75b04b490d0b3519"},{"fixed":"edc7267b59a465c6ae7c5ffac2171c30962bd325"},{"fixed":"4454caa204a2edb19c62754ddb96e5dbca0d2f49"},{"fixed":"c4d6442ac3ed00041fe4e1df715717ed78a7d37f"},{"fixed":"8559b1501f77a5b5d003790bec170ca449e0c674"},{"fixed":"e75717f9aec04355777be41070890c6a815c76df"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72245.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.0.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72245.json"}}],"schema_version":"1.9.0"}
