Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-98110)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 0 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows an attacker with physical access to cause an out-of-bounds read.

The vulnerability exists due to treating a length-bounded value as a NUL-terminated string in btintel firmware ID TLV parsing when processing a received firmware ID TLV without a NUL terminator. An attacker with physical access can provide a firmware ID TLV lacking a NUL terminator to cause an out-of-bounds read.
