CVE-2026-98111— Bluetooth: btintel: validate version TLV value lengths

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：验证版本 TLV 值的长度 btintel_parse_version_tlv() 函数会验证响应中是否存在完整的 TLV（类型-长度-值）结构，但并未确保值的长度满足特定 TLV 类型的要求。因此，过短的值可能通过 get_unaligned_le16()、get_unaligned_le32() 或 memcpy() 引发越界读取（out-of-bounds read）漏洞。 该修复措施拒绝长度小于每种已知 TLV 类型所要求的最小长度的值。同

Vulnerability Title
Bluetooth: btintel: validate version TLV value lengths
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: validate version TLV value lengths btintel_parse_version_tlv() verifies that a complete TLV is present in the response, but it does not ensure that the value is long enough for the specific TLV type. A short value can therefore cause an out-of-bounds read through get_unaligned_le16(), get_unaligned_le32(), or memcpy(). Reject values shorter than the minimum required by each known TLV type. Also reject responses that do not contain the Command Complete Status field.
