CVE-2026-64433

Summary: CVE-2026-64433 affects the Linux kernel Bluetooth MGMT path, where add_device_complete() can perform a use-after-free due to missing locking around hci_conn_params_lookup() and access to params->flags. A concurrent MGMT_OP_REMOVE_DEVICE under hci_dev_lock can free the looked-up hci_co...

CVE-2026-64429 gpio: eic-sprd: use raw_spinlock_t in the irq startup path

In the Linux kernel, the following vulnerability has been resolved: gpio: eic-sprd: use rawspinlockt in the irq startup path sprdeicirqunmask enables the GPIO IRQ and then updates controller state through sprdeicupdate, which takes sprdeic-lock with spinlockirqsave. The callback can be reached fr...

CVE-2026-64429

CVE-2026-64429 : In the Linux kernel, the gpio eic-sprd driver used a sleeping lock during irq startup (spin_lock_irqsave) which could be invoked from an irq_startup path, leading to a sleeping function in an invalid context on PREEMPT_RT. The fix converts the Spreadtrum EIC controller lock to a ...

CVE-2026-64428

In CVE-2026-64428, a Linux kernel vulnerability was fixed in the GPIO SCH irq path. The issue arose because sch_irq_unmask() enables the GPIO IRQ and then updates controller state via sch_irq_mask_unmask(), which uses sch->lock with spin_lock_irqsave(). The callback could reach irq_startup() w...

CVE-2026-64408 Bluetooth: bnep: pin L2CAP connection during netdev registration

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: pin L2CAP connection during netdev registration bnepaddconnection reads the L2CAP connection without holding the channel lock, then passes its HCI device to registernetdev. Controller teardown can clear and relea...

CVE-2026-64408

The CVE concerns the Linux kernel Bluetooth BNEP path: during netdev registration, bnep_add_connection() reads the L2CAP connection without holding the channel lock, and passes the HCI device to register_netdev() while a controller teardown could clear the connection. The published fix is to take...

CVE-2026-64404

CVE-2026-64404 concerns the Linux kernel Bluetooth ISO stack. The vulnerability arises in iso_conn_big_sync(): it drops the socket lock to call hci_get_route(), then re-acquires the lock but may dereference iso_pi(sk)->conn->hcon without re-checking that conn is still valid. While the lock ...

CVE-2026-64396

CVE-2026-64396 concerns the Linux kernel ksmbd subsystem. A use-after-free (UAF) of a struct file_lock can occur during SMB2_LOCK deferred-lock cancellation when a blocking byte-range lock is deferred and the asynchronous work is canceled concurrently. The root cause is a race between de‑queuing ...
