In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Flush cache for PASID table before using it When writing the address of a freshly allocated zero-initialized PASID table to a PASID directory entry, do that after the CPU cache flush for this PASID table, not before it, to avoid the time window when this PASID table may be already used by non-coherent IOMMU hardware while its contents in RAM is still some random old data, not zero-initialized.
Update Linux/Linux to cd75e77125c8a51754ca4cd60b4ca083ed735d1d if you use the affected versions. Test the change in a non-production environment first.

hol-guard supply-chain scaniommu/vt-d: Flush cache for PASID table before using it affects Linux/Linux (generic), Linux/Linux (generic). Severity is high. In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Flush cache for PASID table before using it When writing the address of a freshly allocated zero-initialized PASID table to a PASID directory entry, do that after the CPU cache flush for this PASID table, not before it, to avoid the time window when this PASID table may be already used by non-coherent IOMMU hardware while its contents in RAM is still some random old data, not zero-initialized.
AI coding agents often install or upgrade packages automatically in generic. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
