{"apiVersion":"1.0","identifier":"CVE-2026-72146","description":"In the Linux kernel, the following vulnerability has been resolved: dmaengine: sh: rz-dmac: Move interrupt request after everything is set up Once the interrupt is requested, the interrupt handler may run immediately. Since the IRQ handler can access channel->ch_base, which is initialized only after requesting the IRQ, this may lead to invalid memory access. Likewise, the IRQ thread may access uninitialized data (the ld_free, ld_queue, and ld_active lists), which may also lead to issues. Request the interrupts only after everything is set up. To keep the error path simpler, use dmam_alloc_coherent() instead of dma_alloc_coherent().","publishedAt":"2026-08-15T06:21:32","lastModifiedAt":"2026-08-19T17:21:00","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72146","cvssScore":8.4,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0018,"riskScore":0.85,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72146","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72146","en":"https://www.redsauce.net/en/cves/CVE-2026-72146","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72146","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72146","de":"https://www.redsauce.net/de/cves/CVE-2026-72146","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72146","el":"https://www.redsauce.net/el/cves/CVE-2026-72146"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72146"}}
