Description OSIDB Bzimport 2026-09-25 11:27:08 UTC 
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.
