New $50 Battering RAM Attack Breaks Intel and AMD Cloud Security Protections

A group of academics from KU Leuven and the University of Birmingham has demonstrated a new vulnerability called Battering RAM to bypass the latest defenses on Intel and AMD cloud processors. "We built a simple, $50 interposer that sits quietly in the memory path, behaving transparently during...

The vulnerability of the `tegra_emc_find_node_by_ram_code()` function in the `drivers/memory/tegra/tegra20-emc.c` file of the Linux kernel allows a hacker to access confidential data, compromise its integrity, and cause service failures.

The vulnerability of the tegraemcfindnodebyramcode function in the drivers/memory/tegra/tegra20-emc.c file of the Linux kernel is related to the use of memory after it has been freed. Exploiting this vulnerability could allow an attacker to access confidential data, compromise its integrity, and...

Obelix: Mitigating Side-Channels through Dynamic Obfuscation

Trusted execution environments TEEs offer hardware-assisted means to protect code and data. However, as shown in numerous results over the years, attackers can use side-channels to leak data access patterns and even single-step the code. While the vendors are slowly introducing hardware-based...

CVE-2023-53391 shmem: use ramfs_kill_sb() for kill_sb method of ramfs-based tmpfs

In the Linux kernel, the following vulnerability has been resolved: shmem: use ramfskillsb for killsb method of ramfs-based tmpfs As the ramfs-based tmpfs uses ramfsinitfscontext for the initfscontext method, which allocates fc-sfsinfo, use ramfskillsb to free it and avoid a memory leak...
