CVE-2026-74277

A flaw was found in the Linux kernel's iommu/dma-iommu component. When handling PCI Peer-to-Peer Direct Memory Access P2PDMA cases, an incorrect assignment of the scatterlist length can cause all segments in a multi-segment scatterlist to inherit the length of the first segment. This leads to...

CVE-2026-74277

The CVE-2026-74277 issue is in the Linux kernel iommu/dma-iommu code, specifically the P2PDMA path. In iommu_dma_map_sg(), the DMA length for the current scatterlist segment was erroneously taken from the head entry (sg->length) instead of the current entry (s->length). This causes all P2PD...

CVE-2026-46268

The CVE relates to the Linux kernel PCI/P2PDMA subsystem. A warning in p2pmem_alloc_mmap() was triggered by an assertion VM_WARN_ON_ONCE_PAGE(!page_ref_count(page)) after the initial page refcount was changed to zero by a prior patch. The issue arises only when CONFIG_DEBUG_VM is enabled, produci...
