CVE-2026-99014

The Linux kernel 's Bluetooth stack is vulnerable to a slab-use-after-free in the hci_sync component during PA sync scan setup . Specifically, hci_le_set_ext_scan_param_sync() retrieves a pointer from hci_sent_cmd_data() without holding a reference to the underlying skb. Because the scan worker a...

CVE-2026-99013

The Linux kernel contains a vulnerability in the Bluetooth ISO stack where concurrent listen() calls on the same broadcast socket can lead to a slab-use-after-free condition. This occurs because iso_sock_listen() drops the socket lock before calling iso_listen_bis(), allowing two callers to simul...

CVE-2026-99013 Bluetooth: ISO: Reject concurrent BIS listener setup

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Reject concurrent BIS listener setup isosocklisten drops the socket lock before calling isolistenbis to preserve the hdev-lock ordering. Two concurrent listen calls on the same broadcast socket can therefore both...

EUVD-2026-108806

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Serialize concurrent connect calls isosockconnect checks the socket state before taking the socket lock and drops the lock again before setting up a connection. Two callers can both pass the admission check while...

CVE-2026-99012

The Linux kernel is vulnerable to a slab-use-after-free vulnerability in the Bluetooth ISO stack. The root cause is a race condition in iso_sock_connect(), where the function releases the socket lock before completing the connection setup, allowing concurrent callers to bypass admission checks. T...

Two callers can both pass the admission check while...

CVE-2026-99011

The Linux kernel is affected by a slab-use-after-free vulnerability in the Bluetooth SCO component. The issue arises because sco_recv_scodata() upgrades a weak back-pointer to a strong reference under hdev->lock, but the pointer is cleared by sco_conn_free() without holding that same lock. Thi...
