When processing hardware error events, the driver logs event data as a string without verifying that the received payload is properly null-terminated. A physically proximate attacker or compromised Bluetooth device could exploit this flaw by sending malformed error events to trigger a buffer over-read. This issue primarily leads to information disclosure of adjacent kernel memory into system logs, and could potentially result in a Denial of Service (DoS) if the system crashes.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-98732.json)\n\n**kernel: Bluetooth: btintel: fix buffer over-read in btintel_hw_error()** — rated Low by Red Hat.
