{"apiVersion":"1.0","identifier":"CVE-2026-74566","description":"In the Linux kernel, the following vulnerability has been resolved: keys: make keyring key-chunk byte order agree with keyring_diff_objects() keyring_get_key_chunk() loads description bytes into the index chunk low address first, while keyring_diff_objects() numbers the first differing bit from the low end and folds the absolute byte index into the level without removing the inline-prefix offset the level already carries. The two disagree on byte order and bit position, so the array can be told two keys first differ at a bit that does not differ in the chunk the walker uses, letting crafted descriptions collide into one node. Load the chunk in the order keyring_diff_objects() assumes and drop the inline-prefix length when folding the byte index into the level. This only changes the in-memory ordering used to place keys within a keyring; add, search and read of non-colliding keys are unaffected.","publishedAt":"2026-08-15T13:18:02","lastModifiedAt":"2026-08-19T17:21:11","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74566","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00165,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74566","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74566","en":"https://www.redsauce.net/en/cves/CVE-2026-74566","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74566","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74566","de":"https://www.redsauce.net/de/cves/CVE-2026-74566","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74566","el":"https://www.redsauce.net/el/cves/CVE-2026-74566"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74566"}}
