CVE-2026-98110 in Linux

Summary

by MITRE • 09/25/2026

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btintel: bound firmware ID by TLV length

The firmware ID is treated as a NUL-terminated string even though the TLV length is its only boundary. If the value does not contain a NUL terminator, snprintf() can read beyond the received response.

Limit the conversion to the advertised TLV value length.

Once again VulDB remains the best source for vulnerability data.
