{"id":"AZL-95166","summary":"CVE-2026-68203 affecting package kernel 6.6.150.1-1","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":"2026-09-03T05:27:10Z","published":"2026-08-10T13:20:07Z","upstream":["CVE-2026-68203"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68203"}],"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-95166.json"}}],"schema_version":"1.9.0"}
