{"apiVersion":"1.0","identifier":"CVE-2026-72484","description":"In the Linux kernel, the following vulnerability has been resolved: staging: most: video: avoid double free on video register failure comp_register_videodev() allocates a video_device with video_device_alloc() and releases it if video_register_device() fails. This can double free the video_device when __video_register_device() reaches device_register() and that call fails: video_register_device() -> __video_register_device() -> device_register() fails -> put_device(&vdev->dev) -> v4l2_device_release() -> vdev->release(vdev) -> video_device_release(vdev) comp_register_videodev() -> video_device_release(mdev->vdev) Use video_device_release_empty() while registering the device so that registration failure paths do not free mdev->vdev through vdev->release(). comp_register_videodev() then releases mdev->vdev exactly once on failure. Restore video_device_release() after successful registration so the registered device keeps its normal lifetime handling. This issue was found by a static analysis tool I am developing.","publishedAt":"2026-08-15T06:22:22","lastModifiedAt":"2026-08-17T06:19:16","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72484","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00211,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72484","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72484","en":"https://www.redsauce.net/en/cves/CVE-2026-72484","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72484","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72484","de":"https://www.redsauce.net/de/cves/CVE-2026-72484","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72484","el":"https://www.redsauce.net/el/cves/CVE-2026-72484"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72484"}}
