Kernel memory disclosure via truncated EHT element
Published Aug 15, 2026 · Updated Aug 15, 2026
Out-of-bounds read in Linux kernel 6.14 allows physically proximate attackers to disclose kernel memory through a crafted Wi-Fi beacon. The cfg80211_gen_new_ie() path accepts an undersized EHT Multi-Link element after checking only that it exceeds one byte, then ieee80211_mle_get_mld_id() reads beyond the element without the required type-and-size validation. Normal scanning processes the beacon before authentication or association, enabling disclosure of adjacent kernel memory and repeated kernel oops or panic without user interaction.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
