Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of serialization in the VFIODEVICESETIRQS operation within the vfio/cdx driver. This...

Astra Linux - уязвимость в linux-5.15, linux-6.1
In the Linux kernel, the following vulnerability has been resolved: um: time-travel: fix time corruption In the “basic” time-travel mode without =inf-cpu or =ext, we still encounter timer interrupts. These can occur at arbitrary times, for example, while inside the timerread function, which simpl...

In the Linux kernel, the following vulnerabilities have been resolved: - ice: xsk: disabling TXQ interrupts before flushing the hardware. The function iceqpdis aims to stop a given queue pair that is a target of xsk pool attach/detach. One of the steps involved disabling interrupts on these queue...

In the Linux kernel, the following vulnerability has been resolved: irqchip/realtek-rtl: The refcount leak in mapinterrupts has been fixed. The offindnodebyphandle function returns a node pointer with a incremented refcount. We should use ofnodeput on it when there is no longer a need for it. Thi...

In the Linux kernel, the following vulnerability has been resolved: clockevents: Added missing resets to the nexteventforced flag. The mechanism used to prevent timer interrupts from being missed failed to reset the nexteventforced flag in several locations: - When the state of the clock event...
Astra Linux - уязвимость в linux-6.1
In the Linux kernel, the following vulnerability has been resolved: genirq/msi: The IOMMU IOVA is now stored directly in the msidesc, rather than in the iommucookie. The translation of MSI message addresses using IOMMU involved a two-step process, separated in time: 1 iommudmapreparemsi: A pointe...

In the Linux kernel, the following vulnerabilities have been resolved: scsi: smartpqi: Fix for disablemanagedinterrupts The issue with the registration of blk-mq when the disablemanagedinterrupts parameter is enabled has been corrected. When the default PCIIRQAFFINITY flag is disabled, the driver...
Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Disabling bottom softirqs as part of spinlockirq on PREEMPTRT The function sndpcmgrouplockirq acquires a spinlockt and disables interrupts via spinlockirq. This also implicitly disables the handling of softirqs such as...

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: iwlegacy: Clear stale interrupts before resuming the device. The iwl4965 driver fails when resuming from hibernation on my laptop. The reason seems to be that stale interrupts are not cleared before interrupts are enable...
CVE-2026-43324
A flaw was found in the Linux kernel's dummy-hcd driver. This vulnerability stems from an interrupt synchronization error where emulated interrupts can occur after the system attempts to synchronize interrupt handlers. This timing issue creates a race condition, potentially allowing a callback...
SUSE CVE-2025-40048
In the Linux kernel, the following vulnerability has been resolved: uiohvgeneric: Let userspace take care of interrupt mask Remove the logic to set interrupt mask by default in uiohvgeneric driver as the interrupt mask value is supposed to be controlled completely by the user space. If the mask b...
