CVE-2026-68196

Kernel memory disclosure and crash via length underflow

Published Aug 10, 2026 · Updated Aug 10, 2026

Out-of-bounds read in the Linux WILC1000 Wi-Fi driver allows physically proximate attackers to disclose kernel memory or crash systems. wilc_parse_assoc_resp_info() subtracts a six-byte header from an unchecked response length, wrapping the trailing-data length and copying beyond the association buffer. Exploitation requires WILC1000 hardware to process a malformed association response from a nearby access point; systems without that hardware are unaffected.
