SUSE CVE-2026-43253

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

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...

CVE-2026-43227

A flaw was found in the Linux kernel's clocksource/drivers/shtmu component. This issue arises when the shtmu driver attempts to manage its power and clock states using specific runtime power management functions while holding raw spinlocks. This creates a conflict with other platform drivers that...
