CVE-2026-68350

Memory disclosure or crash via off-by-two bounds check

Published Aug 10, 2026 · Updated Aug 10, 2026

An out-of-bounds read in the carl9170 Wi-Fi driver in Linux 2.6.37 and later allows local users to disclose kernel memory or crash the system. carl9170_tx_process_status() accepts firmware-controlled hdr.ext as its loop limit while an off-by-two comparison permits two reads past valid _tx_status entries. Reachability requires low-privileged local access, an attached AR9170 USB device, and firmware that supplies an hdr.ext value greater than half hdr.len.
