CVE-2026-98458 Bluetooth: ISO: release unused CIS holds after channel attach

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: release unused CIS holds after channel attach hcibindcis and hciconnectcis return one hciconn hold for the ISO layer. A new channel association consumes that hold, which is eventually released by isoconnfree. Ther...

CVE-2026-98458

The Linux kernel Bluetooth ISO layer contains a vulnerability where hci_bind_cis() and hci_connect_cis() return an hci_conn hold that may remain unused. Specifically, the hold is not released when iso_chan_add() returns success for an already attached socket (idempotent case) or returns -EBUSY wh...

CVE-2026-98457 Bluetooth: L2CAP: validate frame length before control and FCS access

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: validate frame length before control and FCS access l2capdatarcv unpacks either a two-byte or four-byte control field without first ensuring that it is present. A short ERTM or streaming-mode frame can therefore...

CVE-2026-98457

A vulnerability in the Linux kernel Bluetooth stack allows for an out-of-bounds read . The l2cap_data_rcv() function fails to verify the presence of two-byte or four-byte control fields before unpacking them, which can be triggered by short ERTM or streaming-mode frames. Additionally, when CRC16 ...

CVE-2026-98456

A race condition exists in the Linux kernel Bluetooth management component within the read_unconf_index_list() function. The vulnerability occurs because hci_dev_list_lock stabilizes list membership but fails to serialize per-device flags during asynchronous controller setup. A worker can transit...

CVE-2026-98454

The Linux kernel contains an out-of-bounds read vulnerability within the smb client component. The smb2_parse_contexts() function fails to limit each record to its Next field before dispatching, allowing a malformed chain to expose bytes beyond the current context. Additionally, the QFid handler ...

CVE-2026-98455

The Linux kernel contains a vulnerability in the Bluetooth RFCOMM stack where a NULL pointer dereference occurs in the RFCOMM_CONNINFO getsockopt handler. When BT_DEFER_SETUP is enabled, the dlc->defer_setup flag remains set even if the session is cleared during rfcomm_recv_disc(). Consequentl...
