{"apiVersion":"1.0","identifier":"CVE-2026-74360","description":"In the Linux kernel, the following vulnerability has been resolved: bpf: Reject exclusive maps for bpf_map_elem iterators Exclusive maps (aka excl_prog_hash) are meant to be reachable only from the single program whose hash matches. This is enforced by check_map_prog_compatibility() when the map is referenced from a program such as signed BPF loaders. A bpf_map_elem iterator, however, binds its target map at attach time in bpf_iter_attach_map() instead of referencing it from the program, so the exclusivity check is never reached. On top of that, the iterator exposes the map value as a writable buffer.","publishedAt":"2026-08-15T06:22:37","lastModifiedAt":"2026-08-17T06:19:30","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74360","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-2026-74360","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74360","en":"https://www.redsauce.net/en/cves/CVE-2026-74360","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74360","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74360","de":"https://www.redsauce.net/de/cves/CVE-2026-74360","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74360","el":"https://www.redsauce.net/el/cves/CVE-2026-74360"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74360"}}
