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-2026-27816

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: move waitonsem out of spinlock With iommu.strict=1, the existing completion wait path can cause soft lockups under stressed environment, as waitonsem busy-waits under the spinlock with interrupts disabled. Move the...

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() ...
