Researchers have discovered two novel attack methods targeting high-performance Intel CPUs that could be exploited to stage a key recovery attack against the Advanced Encryption Standard (AES) algorithm.
The techniques have been collectively dubbed Pathfinder by a group of academics from the University of California San Diego, Purdue University, UNC Chapel
Cybersecurity researchers from ETH Zurich have developed a new variant of the RowHammer DRAM (dynamic random-access memory) attack that, for the first time, successfully works against AMD Zen 2 and Zen 3 systems despite mitigations such as Target Row Refresh (TRR).
"This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems, which greatly increases the attack
Researchers from the Vrije Universiteit Amsterdam have disclosed a new side-channel attack called SLAM that could be exploited to leak sensitive information from kernel memory on current and upcoming CPUs from Intel, AMD, and Arm.
The attack is an end-to-end exploit for Spectre based on a new feature in Intel CPUs called Linear Address Masking (LAM) as well as its analogous
Intel has released fixes to close out a high-severity flaw codenamed Reptar that impacts its desktop, mobile, and server CPUs.
Tracked as CVE-2023-23583 (CVSS score: 8.8), the issue has the potential to "allow escalation of privilege and/or information disclosure and/or denial of service via local access."
Successful exploitation of the vulnerability could also permit a bypass of the CPU's
A group of academics has disclosed a new "software fault attack" on AMD's Secure Encrypted Virtualization (SEV) technology that could be potentially exploited by threat actors to infiltrate encrypted virtual machines (VMs) and even perform privilege escalation.
The attack has been codenamed CacheWarp (CVE-2023-20592) by researchers from the CISPA Helmholtz Center for Information Security and the
Cybersecurity researchers have disclosed details of a trio of side-channel attacks that could be exploited to leak sensitive data from modern CPUs.
Called Collide+Power (CVE-2023-20583), Downfall (CVE-2022-40982), and Inception (CVE-2023-20569), the novel methods follow the disclosure of another newly discovered security vulnerability affecting AMD's Zen 2 architecture-based processors known as
A group of researchers has revealed details of a new vulnerability affecting Intel CPUs that enables attackers to obtain encryption keys and other secret information from the processors.
Dubbed ÆPIC Leak, the weakness is the first-of-its-kind to architecturally disclose sensitive data in a manner that's akin to an "uninitialized memory read in the CPU itself."
"In contrast to transient execution
With speculative execution attacks remaining a stubbornly persistent vulnerability ailing modern processors, new research has highlighted an "industry failure" to adopt mitigations released by AMD and Intel, posing a firmware supply chain threat.
Dubbed FirmwareBleed by Binarly, the information leaking assaults stem from the continued exposure of microarchitectural attack surfaces on the part of
Security researchers have uncovered yet another vulnerability affecting numerous older AMD and Intel microprocessors that could bypass current defenses and result in Spectre-based speculative-execution attacks.
Dubbed Retbleed by ETH Zurich researchers Johannes Wikner and Kaveh Razavi, the issue is tracked as CVE-2022-29900 (AMD) and CVE-2022-29901 (Intel), with the chipmakers releasing software
