In this scenario addr_to_vb_xa()\nhash function can return an index which accesses to not-possible and not\nsetup CPU area using per_cpu() macro.  This results in an oops on SPARC.\n\nA per-cpu vmap_block_queue is also used as hash table, incorrectly\nassuming the cpu_possible_mask has no gaps.  Fix it by adjusting an index\nto a next possible CPU.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/28acd531c9a365dac01b32e6bc54aed8c1429bcb","https://git.kernel.org/stable/c/47f9b6e49b422392fb0e348a65eb925103ba1882","https://git.kernel.org/stable/c/a34acf30b19bc4ee3ba2f1082756ea2604c19138","https://git.kernel.org/stable/c/28acd531c9a365dac01b32e6bc54aed8c1429bcb","https://git.kernel.org/stable/c/47f9b6e49b422392fb0e348a65eb925103ba1882"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:53:51.317825789+00:00"},"epss":{"cve":"CVE-2024-41032","score":0.003,"percentile":0.2271,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
