{"apiVersion":"1.0","identifier":"CVE-2026-99095","description":"In the Linux kernel, the following vulnerability has been resolved: drm/vc4: drain the hangcheck timer and works on V3D unbind Nothing stops the hangcheck timer that submitted jobs arm, or the job_done_work that the render-done interrupt queues, at teardown: vc4_irq_disable() cancels only overflow_mem_work, and vc4_gem_destroy() runs from the drm-managed release, after vc4_v3d_unbind() has already uninstalled the V3D interrupt and cleared vc4->v3d. A timer still armed by then reads V3D registers through the NULL vc4->v3d pointer, and the late callbacks run on the vc4_dev embedding them after it has been freed. Drain them in vc4_v3d_unbind(): shut the timer down and cancel reset_work before the interrupt is taken down, because its vc4_irq_reset() re-enables it, then flush job_done_work so that completions queued at teardown still release their jobs. This issue was found by an in-house static analysis tool.","publishedAt":"2026-10-26T15:16:48","lastModifiedAt":"2026-10-30T13:21:44","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99095","cvssScore":null,"cvssVector":null,"epssProbability":0.00168,"riskScore":null,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99095","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99095","en":"https://www.redsauce.net/en/cves/CVE-2026-99095","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99095","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99095","de":"https://www.redsauce.net/de/cves/CVE-2026-99095","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99095","el":"https://www.redsauce.net/el/cves/CVE-2026-99095"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99095"}}
