CVE-2026-74529 Bluetooth: hci_sync: hold conn in hci_connect_pa_sync() callback

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: hold conn in hciconnectpasync callback There is theoretical UAF if the conn is freed while the hcisync task is running. Hold refcount to avoid that...

PT-2026-72987

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: avoid deadlocks in iso sock timeout iso sock timeout takes lock sock, so sync disabling the timer while holding that lock may deadlock. iso sock timeout may also run concurrently with iso conn del, which leads to...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci sync: hold conn in hci connect big sync callback There is theoretical UAF if the conn is freed while the hci sync task is running. Hold refcount to avoid that. Handle NULL hcon, return 0 + do nothing to match the...

CVE-2026-68393

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: extend connhash lookup critical sections Using RCU-protected pointers outside the critical sections without refcount is incorrect and may result to UAF. Extend critical section to cover both hciconnhash lookup...

CVE-2026-68394

In CVE-2026-68394, the Linux kernel Bluetooth MGMT path had a use-after-free in conn_update_sync triggered by MGMT_OP_LOAD_CONN_PARAM queuing a param update. The queued work incorrectly kept a borrowed hci_conn_params pointer; if userspace freed the entry before the callback ran, a use-after-free...

CVE-2026-68393 Bluetooth: hci_sync: extend conn_hash lookup critical sections

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: extend connhash lookup critical sections Using RCU-protected pointers outside the critical sections without refcount is incorrect and may result to UAF. Extend critical section to cover both hciconnhash lookup...

CVE-2026-64405

A flaw was found in the Linux kernel's Bluetooth subsystem, specifically within the hciconn module. This vulnerability occurs when the hciabortconn function attempts to process a pending connection while a critical pointer is unexpectedly null. This can lead to a null pointer dereference, causing...

CVE-2026-64405

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciconn: Fix null ptr deref in hciabortconn hciabortconn read hciskbeventhdev-sentcmd when a connection was pending, but hdev-sentcmd can be NULL while reqstatus is still HCIREQPEND, leading to a NULL pointer dereferen...

CVE-2026-64433

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Fix UAF of hciconnparams in adddevicecomplete adddevicecomplete runs from the hcicmdsyncwork kworker, which holds only hcireqsynclock and not hcidevlock. It calls hciconnparamslookup and then dereferences the...

CVE-2026-64433

CVE-2026-64433 is a Use-After-Free in the Linux kernel's Bluetooth MGMT subsystem (net/bluetooth/mgmt.c). The function add_device_complete() calls hci_conn_params_lookup() and reads params->flags without holding hci_dev_lock, allowing a concurrent MGMT_OP_REMOVE_DEVICE to free the underlying o...

CVE-2026-64404

CVE-2026-64404 is a NULL pointer dereference in the Linux kernel's Bluetooth ISO subsystem , specifically in the iso_conn_big_sync() function. The function drops the socket lock to call hci_get_route() and re-acquires it, but dereferences iso_pi(sk)->conn->hcon without re-validating that co...

In the Linux kernel, the following vulnerability has been resolved: bpf: Drop tasktoinode and inetconnestablished from lsm sleepable hooks bpflsmtasktoinode is called under rcureadlock and bpflsminetconnestablished is called from softirq context, so neither hook can be used by sleepable LSM...

CVE-2026-63865

A flaw was found in the Linux kernel. The Berkeley Packet Filter BPF Linux Security Modules LSM feature incorrectly registered certain hooks, tasktoinode and inetconnestablished, as available for sleepable programs. These hooks are invoked in critical system contexts where program sleeping is not...
