{"apiVersion":"1.0","identifier":"CVE-2026-74422","description":"In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: inno-hdmi: Switch to drmm_kzalloc() Driver makes use of drmm_encoder_init() to initialize the encoder and automatically handle the cleanup by registering drm_encoder_cleanup() with drmm_add_action(). However, the internal structure containing the encoder part gets allocated with devm_kzalloc(), which happens while component_bind_all() is being called from Rockchip DRM driver. The component framework further ensures it is deallocated as part of releasing all the resources claimed during bind, which is triggered from component_unbind_all(). When the reference to the DRM device gets eventually dropped via drm_dev_put() in rockchip_drm_unbind(), drmm_encoder_alloc_release() attempts to access the now released encoder structure, leading to use-after-free. Ensure driver-s internal structure is still reachable on encoder cleanup by switching from a device-managed allocation to a drm-managed one.","publishedAt":"2026-08-15T06:22:44","lastModifiedAt":"2026-08-17T06:19:37","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74422","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00145,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74422","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74422","en":"https://www.redsauce.net/en/cves/CVE-2026-74422","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74422","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74422","de":"https://www.redsauce.net/de/cves/CVE-2026-74422","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74422","el":"https://www.redsauce.net/el/cves/CVE-2026-74422"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74422"}}
