{"apiVersion":"1.0","identifier":"CVE-2026-80627","description":"In the Linux kernel, the following vulnerability has been resolved: MIPS: mm: Fix out-of-bounds write in maar_res_walk() maar_res_walk() uses wi->num_cfg as the index into the fixed-size wi->cfg array, but checks whether the array is full only after it has filled the selected entry. If walk_system_ram_range() reports more than 16 memory ranges, the overflow call writes one struct maar_config past the end of the array before WARN_ON() prevents num_cfg from advancing. Move the full-array check before taking the array slot and return non-zero when the scratch array is full, so walk_system_ram_range() terminates the walk instead of invoking the callback for further ranges.","publishedAt":"2026-08-28T08:16:46","lastModifiedAt":"2026-08-28T08:16:46","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80627","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00176,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80627","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80627","en":"https://www.redsauce.net/en/cves/CVE-2026-80627","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80627","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80627","de":"https://www.redsauce.net/de/cves/CVE-2026-80627","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80627","el":"https://www.redsauce.net/el/cves/CVE-2026-80627"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80627"}}
