CVE-2026-64465

In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Fix sleep in atomic context in xhcifreestreams When a USB device with active stream endpoints is disconnected, xhcifreestreams is called from the hubevent workqueue to free the stream resources. It calls...

CVE-2026-64464

Consolidated details show CVE-2026-64464 affects the Linux kernel xhci sideband path: xhci_ring_to_sgtable() allocates a temporary pages array used to build an sg_table via sg_alloc_table_from_pages(). On success, the temporary array isn’t freed, causing a leak each time a sideband client uses an...

CVE-2026-64462 PCI: altera: Fix resource leaks on probe failure

In the Linux kernel, the following vulnerability has been resolved: PCI: altera: Fix resource leaks on probe failure The chained IRQ handler is set during probe, but is only removed during the driver remove. If pcihostprobe fails, the handler and INTx IRQ domain remain set even though the...

CVE-2026-64463 usb: typec: tcpci_rt1711h: unregister TCPCI port with devres

In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpcirt1711h: unregister TCPCI port with devres rt1711hprobe registers the TCPCI port before requesting the interrupt and enabling alert interrupts. If either of those later steps fails, the probe function returns...

CVE-2026-64454

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: run gadget disconnect from sleepable suspend context dwc3gadgetsuspend takes dwc-lock with IRQs disabled and then calls dwc3disconnectgadget. For async callbacks that helper only uses plain spinunlock/spinlock, so the...

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-2026-64429 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 affects the Spreadtrum EIC GPIO IRQ controller driver in the Linux kernel. The root cause is that sprd_eic_irq_unmask() calls sprd_eic_update(), which acquires a lock via spin_lock_irqsave(). On PREEMPT_RT kernels, a regular spinlock_t becomes a sleeping lock, but the code path is ...

CVE-2026-64428

CVE-2026-64428 affects the SCH GPIO controller (gpio:sch) in the Linux kernel. The root cause is that sch_irq_unmask() acquires sch->lock via spin_lock_irqsave(), which on PREEMPT_RT becomes a sleeping lock. This lock is reached from irq_startup(), a non-sleepable context, triggering a "sleepi...
