CVE-2026-64328
A flaw was found in the Linux kernel's USB gadget subsystem. Specifically, a DMA Direct Memory Access fence leak exists in the ffs module's ffsdmabuftransfer function. This issue causes ffsdmafence objects to be allocated without their initial reference being properly released. Repeated...

CVE-2026-64124
CVE-2026-64124 concerns the Linux kernel net: devmem: bind via dma-buf with non-page-aligned size or SG length. The issue arises because net_devmem_bind_dmabuf() trusts dmabuf->size and sg_dma_len() to be multiples of PAGE_SIZE without checking, causing an out-of-bounds access: tx_vec is sized...
CVE-2026-64042
In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Check BAR resources before exporting a DMABUF A DMABUF exports access to BAR resources and, although they are requested at startup time, we need to ensure they really were reserved before exporting. Otherwise, it's...
