CVE-2026-74629

In the Linux kernel, the following vulnerability has been resolved: net/dibs: Correct freeing of dmbclientidarr A dibs device interrupt handler can be active after dibsdevdel and may still access dmbclientidarr. UAF In case of a failure in dibsdevadd being called by dibslodevprobe dmbclientidarr ...

CVE-2026-74617

In the Linux kernel, the following vulnerability has been resolved: dibs: initialise dibs-lock in dibsdevalloc dibs-lock is initialised by dibsdevadd, but a dibs device can already take interrupts before that call: ismprobe runs ismdevinit, and hence requestirq, before it calls dibsdevadd. No...

CVE-2026-74690

CVE-2026-74690 is a Use-After-Free vulnerability in the Linux kernel 's s390/ism (Interrupt Sharing Module) subsystem. An ISM interrupt handler can remain active in parallel with ism_dev_exit(), accessing already-freed sba and ieq data structures. The fix ensures that after unregister_ieq() no ne...

CVE-2026-74629

CVE-2026-74629 affects the Linux kernel in the net/dibs subsystem. Two memory management flaws exist: a use-after-free occurs because a dibs device interrupt handler can remain active after dibs_dev_del() and still access dmb_clientid_arr, and a double free occurs when dibs_dev_add() fails during...

CVE-2026-74617

CVE-2026-74617 is a Linux kernel vulnerability in the DIBS (Distributed Interface Bus System) driver. The root cause is that dibs->lock was initialized in dibs_dev_add(), but the interrupt handler ism_handle_irq() could fire earlier—after request_irq() in ism_dev_init()—and unconditionally acq...

EUVD-2026-64554

In the Linux kernel, the following vulnerability has been resolved: dibs: initialise dibs-lock in dibsdevalloc dibs-lock is initialised by dibsdevadd, but a dibs device can already take interrupts before that call: ismprobe runs ismdevinit, and hence requestirq, before it calls dibsdevadd. No...

CVE-2026-74617 dibs: initialise dibs->lock in dibs_dev_alloc()

In the Linux kernel, the following vulnerability has been resolved: dibs: initialise dibs-lock in dibsdevalloc dibs-lock is initialised by dibsdevadd, but a dibs device can already take interrupts before that call: ismprobe runs ismdevinit, and hence requestirq, before it calls dibsdevadd. No...

In the Linux kernel, the following vulnerability has been resolved: s390/ism: Fix UAF of sba and ieq during ism dev exit A ism interrupt handler can be active in parallel with ism dev exit, accessing freed data structures. No new interrupts will be generated after unregister ieq. Drain ongoing...

CVE-2026-74468

A flaw was found in the Linux kernel's GPIO PCH driver. On systems configured with PREEMPTRT, a local attacker could trigger a specific interrupt handler pchirqtype in a non-sleepable context. This improper use of a spinlock, which attempts to acquire a sleeping lock in an atomic context, can lea...

CVE-2026-72384

A flaw was found in the Linux kernel's irqchip/ts4800 driver. The driver fails to properly clear a chained interrupt handler when it is removed. This oversight leaves a dangling handler that could be invoked if the parent interrupt fires after the driver has been unloaded. Such an event could lea...

CVE-2026-74309

A flaw was found in the Linux kernel's vdpa/octeonep component. This vulnerability involves an incorrect mapping of Interrupt Request IRQ numbers to processing rings within the interrupt handler. The system incorrectly calculates the IRQ index, which can lead to misdirected or mishandled...

CVE-2026-74309

In the Linux kernel, the following vulnerability has been resolved: vdpa/octeonep: fix IRQ-to-ring mapping in interrupt handler Look up the IRQ index in octhw-irqs instead of assuming irq - irqs0. This supports non-contiguous IRQ numbers and avoids incorrect ring indexing when irqs0 is not the ba...
