Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Wifi: ath11k: The affinity hint was cleared before calling ath11kpcicfreeirq in the error path. If a shared IRQ is used by the driver due to platform limitations, then the IRQ affinity hint is set correctly after the allocation o...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of vgicallocateprivateirqslocked in the KVM ARM64 virtual GIC, causing it to exit...

Linux Distros Unpatched Vulnerability : CVE-2026-43087

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: pinctrl: mcp23s08: Disable all pin interrupts during probe A chip being probed may have the...

CVE-2026-43253

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit AMD component. When the system operates under a stressed environment with iommu.strict=1 enabled, a busy-wait operation within the waitonsem function can occur while holding a spinlock with interrupts disabled. This...

EUVD-2026-27584

In the Linux kernel, the following vulnerability has been resolved: pinctrl: mcp23s08: Disable all pin interrupts during probe A chip being probed may have the interrupt-on-change feature enabled on some of its pins, for example after a reboot. This can cause the chip to generate interrupts for...

CVE-2026-43253

CVE-2026-43253 relates to the Linux kernel IOMMU AMD component. When iommu.strict=1, the wait_on_sem() busy-wait runs inside a spinlock with interrupts disabled, risking soft lockups under load. The fix moves the completion wait out of the spinlock in iommu_completion_wait(), since wait_on_sem() ...

CVE-2026-43087

In the Linux kernel, the following vulnerability has been resolved: pinctrl: mcp23s08: Disable all pin interrupts during probe A chip being probed may have the interrupt-on-change feature enabled on some of its pins, for example after a reboot. This can cause the chip to generate interrupts for...

CVE-2026-43095

In CVE-2026-43095, the Linux kernel ASoC SDCA subsystem fixes an IRQ cleanup flaw. IRQs are currently enabled via sdca_irq_populate() from component probe using devm_request_threaded_irq(), which can cause IRQs to persist after a sound card teardown. Some IRQ handlers hold references to the card ...

CVE-2026-43087

The CVE-2026-43087 issue affects the Linux kernel’s pinctrl/mcp23s08 driver. Root cause: during probe, reg_defaults were removed from the regmap, causing the MCP_GPINTEN value to be read from the chip (possibly non-zero) and trigger a nested IRQ handler that may not exist, leading to a kernel cra...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the mcp23s08 chip not disabling all pin interrupts during detection. This could lead to interrupts bein...
