ScaleDisturb: Exploiting Temporal Asymmetry to Amplify Read Disturbance in Modern DRAM Chips

DRAM suffers from read disturbance phenomena e.g., RowHammer and RowPress, where repeatedly accessing or continuously keeping open a DRAM row aggressor row induces bitflips in other physically nearby unaccessed rows victim rows. The disturbance mechanism is practically exploitable from the softwa...

Thunderhammer: Rowhammer Bitflips Via PCIe and Thunderbolt (USB-C)

In recent years, Rowhammer has attracted significant attention from academia and industry alike. This technique, first published in 2014, flips bits in memory by repeatedly accessing neighbouring memory locations. Since its discovery, researchers have developed a substantial body of work exploiti...

SUSE CVE-2024-56771

In the Linux kernel, the following vulnerability has been resolved: mtd: spinand: winbond: Fix 512GW, 01GW, 01JW and 02JW ECC information These four chips: W25N512GW W25N01GW W25N01JW W25N02JW all require a single bit of ECC strength and thus feature an on-die Hamming-like ECC engine. There is no...

New Rowhammer Technique

Rowhammer is an attack technique involving accessing -- thats "hammering" -- rows of bits in memory, millions of times per second, with the intent of causing bits in neighboring rows to flip. This is a side-channel attack, and the result can be all sorts of mayhem. Well, there is a new enhancemen...
