CVE-2026-8169

CVE-2026-8169 concerns ExtremeXOS (EXOS) where the privileged debug-mode access relies on a challenge-response mechanism. The challenge is generated from an insufficiently random source, allowing, under certain conditions, an attacker to predict the expected response and activate debug-mode witho...

CVE-2026-64152

CVE-2026-64152 affects the Linux kernel iommu path. The issue arises when an unmap error in the iommu_debug flow occurs in an error path that did not establish the original iommu_debug_map, causing mis-tracing and unbalanced tracking. Fix: move the unmap error handling into iommu_map_nosync() and...
