{"apiVersion":"1.0","identifier":"CVE-2026-72181","description":"In the Linux kernel, the following vulnerability has been resolved: mips: sched: Fix CPUMASK_OFFSTACK memory corruption This patch addresses a critical memory management flaw. When CONFIG_CPUMASK_OFFSTACK is enabled, cpumask_var_t is a pointer. Consequently, sizeof(new_mask) evaluates to the pointer size, causing copy_from_user() to clobber the mask pointer. Furthermore, the old logic performed copy_from_user() before allocating the mask. Fix this by allocating new_mask first. To handle variable-sized user masks correctly, use cpumask_size() to truncate overly large user masks or pad undersized masks with zeros before copying the data directly into the allocated buffer.","publishedAt":"2026-08-15T06:21:36","lastModifiedAt":"2026-08-19T17:21:00","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72181","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00164,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72181","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72181","en":"https://www.redsauce.net/en/cves/CVE-2026-72181","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72181","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72181","de":"https://www.redsauce.net/de/cves/CVE-2026-72181","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72181","el":"https://www.redsauce.net/el/cves/CVE-2026-72181"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72181"}}
