In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Adjust PHY FSM transition to TXEN-to-PLLON for TMDS on DCN35 Why A backport of the change made for DCN401 that addresses an issue where we turn off the PHY PLL when disabling TMDS output, which causes the OTG to...

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() ...
