CVE-2026-64168

A flaw was found in the Linux kernel's spi-sprd driver. This vulnerability occurs when the driver attempts to release Direct Memory Access DMA channels after a DMA setup failure during the probe phase. Without properly checking if DMA is enabled, the driver may try to dereference an invalid point...

CVE-2026-64042

A flaw was found in the Linux kernel's vfio/pci subsystem. This vulnerability occurs because the Direct Memory Access Buffer DMABUF export mechanism does not adequately verify if Base Address Register BAR resources are properly reserved before allowing access. A local attacker could exploit this ...
