{"id":"CVE-2026-68203","summary":"media: vivid: fix cleanup bugs in vivid_init()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: vivid: fix cleanup bugs in vivid_init()\n\nWhen platform_device_register() fails in vivid_init(), the embedded\nstruct device in vivid_pdev has already been initialized by\ndevice_initialize(), but the failure path jumps to free_output_strings\nwithout dropping the device reference for the current platform device:\n\n  vivid_init()\n    -\u003e platform_device_register(&vivid_pdev)\n       -\u003e device_initialize(&vivid_pdev.dev)\n       -\u003e setup_pdev_dma_masks(&vivid_pdev)\n       -\u003e platform_device_add(&vivid_pdev)\n\nThis leads to a reference leak when platform_device_register() fails.\nFix this by calling platform_device_put() before jumping to the common\ncleanup path.\n\nAlso, the unreg_driver label incorrectly calls\nplatform_driver_register() instead of platform_driver_unregister(),\nwhich breaks cleanup when workqueue creation fails after successful\ndriver registration. Fix that as well.\n\nThe reference leak was identified by a static analysis tool I developed\nand confirmed by manual review. The incorrect cleanup call was found\nduring code inspection.","modified":"2026-08-12T04:18:46.489483948Z","published":"2026-08-10T12:00:22.319Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68203.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1349af7f87df57940619f5b87990b799dac9ed8a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4385092a86b94e1f332db35a3766108978c0722f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6d51ad8f1c50c50d1abcc97fd243179967184c6a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a07c179a92e949172ca52f6d4a13202ea88cd4b7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68203.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68203"},{"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":"f46d740fb0258982f00ffdbddc6486e674edafb5"},{"fixed":"4385092a86b94e1f332db35a3766108978c0722f"},{"fixed":"1349af7f87df57940619f5b87990b799dac9ed8a"},{"fixed":"6d51ad8f1c50c50d1abcc97fd243179967184c6a"},{"fixed":"a07c179a92e949172ca52f6d4a13202ea88cd4b7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68203.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.1.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68203.json"}}],"schema_version":"1.9.0"}
