EUVD-2026-86941

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 t...

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

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.

CVE-2026-98110

The Linux kernel contains a vulnerability in the Bluetooth btintel driver where the firmware ID is incorrectly treated as a NUL-terminated string. Because the TLV length is the only actual boundary, the snprintf() function may read beyond the received response if a NUL terminator is missing. The ...

CVE-2026-98111

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: validate version TLV value lengths btintelparseversiontlv 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...

CVE-2026-98107

The Linux kernel Bluetooth L2CAP component contains an out-of-bounds write vulnerability in l2cap_ecred_connect. The root cause is in l2cap_chan_connect(), where the check for pending ECRED channels incorrectly counts only deferred channels. Specifically, if 6 L2CAP sockets are connected in a spe...
