CVE-2026-53283

CVE-2026-53283 concerns the Linux kernel AMD IOMMU driver. The issue arises when the inlined check path in __rlookup_amd_iommu() performs an out-of-bounds read on rlookup_table[devid] for a PCI device whose BDF isn’t described by IVRS. Prior to the commit that changed kvalloc() usage, the over-re...
