| bt_hfp_hf_connect() in subsys/bluetooth/host/classic/hfp_hf.c allocates the per-connection HFP Hands-Free object with hfp_hf_create(), which starts an SDP discovery by passing the object's embedded hf->sdp_param to bt_sdp_discover(). That call links the caller-owned parameter block into the SDP client's request list (session->reqs in subsys/bluetooth/host/classic/sdp.c). If the subsequent bt_rfcomm_dlc_connect() then failed, the affected code wiped the entire object with (void)memset(new_hf, 0, sizeof(*new_hf)) while that discovery was still outstanding, zeroing the sys_snode_t _node that is still linked in the SDP client's list along with the request's func, uuid and pool pointers, and zeroing the hf->slc_work work item that may already be queued on the system workqueue. The discovery could not be retracted instead: bt_sdp_discover_cancel() is declared in include/zephyr/bluetooth/classic/sdp.h but has no implementation.
The failing branch is reachable with peer-supplied input. The documented use of bt_hfp_hf_connect() is to pass the RFCOMM channel read out of the remote Audio Gateway's SDP record; neither bt_sdp_get_proto_param() nor bt_hfp_hf_connect() range-checks that value, so a remote device advertising an HFP AG record with an RFCOMM channel outside 1-30 makes bt_rfcomm_dlc_connect() return -EINVAL and drives the local device into the wipe. The same branch is reached without any application misuse when the remote peer controls connection timing, for example when the RFCOMM session is in BT_RFCOMM_STATE_DISCONNECTING or the ACL is dropped between object creation and the RFCOMM call.
Once the object has been wiped, the Bluetooth host continues to use it: sdp_client_alloc_buf() dereferences session->param->pool, which is now NULL, and the SDP receive paths call session->param->func() through a null function pointer, neither of which is NULL-checked. Because the wipe also clears hf->acl, the pool slot is considered free and a retry or an incoming HFP connection re-appends the same still-linked list node, turning session->reqs into a self-referential list that the host's list walkers never leave. The result is a fault or an unrecoverable hang in the Bluetooth host thread; the stray indirect call is through an all-zero pointer whose target the attacker does not control, so the practical impact is denial of service.
The fix keeps the object allocated and marks it with a new BT_HFP_HF_FLAG_RELEASING flag, letting bt_hfp_hf_discover_cb() release it once the discovery completes instead of destroying it under the SDP client. Only builds with CONFIG_BT_CLASSIC and CONFIG_BT_HFP_HF enabled are affected. |

| In the Linux kernel, the following vulnerability has been resolved:
drm/vc4: drain the hangcheck timer and works on V3D unbind
Nothing stops the hangcheck timer that submitted jobs arm, or the
job_done_work that the render-done interrupt queues, at teardown:
vc4_irq_disable() cancels only overflow_mem_work, and vc4_gem_destroy()
runs from the drm-managed release, after vc4_v3d_unbind() has already
uninstalled the V3D interrupt and cleared vc4->v3d. A timer still armed
by then reads V3D registers through the NULL vc4->v3d pointer, and the
late callbacks run on the vc4_dev embedding them after it has been
freed.
Drain them in vc4_v3d_unbind(): shut the timer down and cancel
reset_work before the interrupt is taken down, because its
vc4_irq_reset() re-enables it, then flush job_done_work so that
completions queued at teardown still release their jobs.

Bluetooth: hci_sync: fix UAF in hci_le_create_cis_sync
hci_le_create_cis_sync() dereferences conn->conn_timeout after releasing
both rcu_read_lock() and hci_dev_lock(hdev). The conn pointer was
obtained from an RCU-protected iteration over hdev->conn_hash.list and
is not valid once these locks are dropped. A concurrent disconnect can
free the hci_conn between the unlock and the dereference, causing a
use-after-free read.
The cancellation mechanism in hci_conn_del() cannot prevent this because
hci_le_create_cis_pending() queues hci_create_cis_sync with data=NULL:
hci_cmd_sync_queue(hdev, hci_create_cis_sync, NULL, NULL);
While hci_conn_del() dequeues with data=conn:
hci_cmd_sync_dequeue(hdev, NULL, conn, NULL);
Since NULL != conn, the lookup in _hci_cmd_sync_lookup_entry() never
matches, and the pending work item is not cancelled.
Fix this by saving conn->conn_timeout into a local variable while the
locks are still held, so the stale conn pointer is never dereferenced
after unlock.
This is the same class of bug as the one fixed by commit 035c25007c9e
("Bluetooth: hci_sync: Fix UAF on le_read_features_complete") which
addressed the identical pattern in a different function.
