{"apiVersion":"1.0","identifier":"CVE-2026-74602","description":"In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Initialise reader page order in rb_allocate_cpu_buffer() In rb_allocate_cpu_buffer(), bpage->order was omitted, leaving it as 0. This is an issue for a ring-buffer with subbufs bigger than PAGE_SIZE if when freed: free_buffer_page() relies on this value. Align the value with the actual allocation size (buffer::subbuf_order).","publishedAt":"2026-08-22T16:16:32","lastModifiedAt":"2026-08-23T13:16:46","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74602","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00168,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74602","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74602","en":"https://www.redsauce.net/en/cves/CVE-2026-74602","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74602","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74602","de":"https://www.redsauce.net/de/cves/CVE-2026-74602","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74602","el":"https://www.redsauce.net/el/cves/CVE-2026-74602"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74602"}}
