CVE-2024-27410

Kernel memory disclosure and corruption via mesh transition

Published May 17, 2024 · Updated Aug 5, 2026

Type confusion in the Linux kernel nl80211 interface allows local users to disclose and corrupt kernel memory through crafted netlink requests. A simultaneous mesh-ID and interface-type update overwrites the active member of wdev->u, leaving an attacker-controlled SSID length for unchecked copies. A low-privileged user can obtain namespace-scoped CAP_NET_ADMIN, and triggering the flaw can expose adjacent heap data, corrupt kernel objects, or panic the host.
