CVE-2024-38562

Kernel warning via out-of-bounds scan-request address calculation

Published Jun 19, 2024 · Updated May 11, 2026

Out-of-bounds address calculation in Linux kernel 6.6 through 6.9.2 allows local users to trigger a runtime bounds-check warning. The nl80211 scan-request allocator uses request->channels before setting request->n_channels and derives trailing-object addresses from a one-past-the-end channels index. Reaching the flaw requires local access capable of issuing nl80211 scan requests; the Linux notice reports the warning but no further concrete consequence.
