CnC-PRAC: Coalesce, Not Cache, Per Row Activation Counts for an Efficient In-DRAM Rowhammer Mitigation

JEDEC has introduced the Per Row Activation Counting PRAC framework for DDR5 and future DRAMs to enable precise counting of DRAM row activations using per-row activation counts. While recent PRAC implementations enable holistic mitigation of Rowhammer attacks, they impose slowdowns of up to 10% d...

CVE-2025-38064

In the Linux kernel, the following vulnerability has been resolved: virtio: break and reset virtio devices on deviceshutdown Hongyu reported a hang on kexec in a VM. QEMU reported invalid memory accesses during the hang. Invalid read at addr 0x102877002, size 2, region 'null', reason: rejected...

CVE-2025-38064

The CVE-2025-38064 entry concerns the Linux kernel virtio subsystem, specifically virtio-console, where devices continue to write to MMIO after the underlying virtio-pci device is reset, causing hangs in kexec-in-VM scenarios. The issue is mitigated by the kernel fix that breaks all virtio device...
