When the address falls in a gap\nbefore the returned VMA, (ptr & PAGE_MASK) - vma->vm_start underflows,\ncorrupting the DMA address sent to the DSP.\n\nReplace find_vma() with vma_lookup(), which returns NULL when the address\nis not contained within any VMA.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/2d0f47e27c1fa718b29c69aa7c96a2c5161bc2c2","https://git.kernel.org/stable/c/464c6ad2aa16e1e1df9d559289199356493d1e00","https://git.kernel.org/stable/c/53e06f8a3c2b085c31bf1284e2ebcb8036e99625","https://git.kernel.org/stable/c/708c17b52c60fe7a57e73b495bdee50f58feb48c","https://git.kernel.org/stable/c/7ba7b30ddb04646d4d638f4d8c4718a304bbbddd"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-53159","score":0.00129,"percentile":0.02537,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
