{"apiVersion":"1.0","identifier":"CVE-2026-80685","description":"In the Linux kernel, the following vulnerability has been resolved: mm/util: don-t read __page_2 for order-1 folios in snapshot_page() snapshot_page() currently reads __page_2 after checking nr_pages > 1, but it should only do so when nr_pages > 2. If an order-1 folio is allocated at the end of a vmemmap section, __page_2 will not exist and reading it will cause a fault. During DLPAR memory remove on a 22 TB ppc64le LPAR, snapshot_page() oopsed on the page isolation path while reading an order-1 folio-s __page_2 from an adjacent absent section (unmapped vmemmap). Fix this to avoid reading memmap that doesn-t exist (e.g., a vmemmap hole).","publishedAt":"2026-08-28T08:16:53","lastModifiedAt":"2026-08-28T08:16:53","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80685","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00166,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80685","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80685","en":"https://www.redsauce.net/en/cves/CVE-2026-80685","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80685","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80685","de":"https://www.redsauce.net/de/cves/CVE-2026-80685","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80685","el":"https://www.redsauce.net/el/cves/CVE-2026-80685"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80685"}}
