CVE-2026-98110— Bluetooth: btintel: bound firmware ID by TLV length

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： 蓝牙：btintel：通过 TLV 长度限制固件 ID 的范围 尽管 TLV（类型-长度-值）的长度是固件 ID 的唯一边界，但代码却将其视为以 NUL 结尾的字符串。如果该值中不包含 NUL 终止符， 可能会读取超出接收到的响应范围的数据。 修复措施是将转换操作限制在所声明的 TLV 值长度范围内。

Vulnerability Title
Bluetooth: btintel: bound firmware ID by TLV length
Source: CVE Program / CVE List V5
Vulnerability Description
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.
