New Spectre v2 attack impacts Linux systems on Intel CPUs
2024-04-10 17:19

Researchers have demonstrated the "First native Spectre v2 exploit" for a new speculative execution side-channel flaw that impacts Linux systems running on many modern Intel processors. Spectre V2 is a new variant of the original Spectre attack discovered by a team of researchers at the VUSec group from VU Amsterdam.

Linux kernel logic allowed Spectre attack on 'major cloud provider'
2023-04-14 06:27

"The kernel failed to protect applications that attempted to protect against Spectre v2, leaving them open to attack from other processes running on the same physical core in another hyperthread," the vulnerability disclosure explains. Linux kernel 6.0 debuts, Linus Torvalds teases 'core new things' coming in version 6.1 Older AMD, Intel chips vulnerable to data-leaking 'Retbleed' Spectre variant Apple gets lawsuit over Meltdown and Spectre dismissed Boffins release tool to decrypt Intel microcode.

Older AMD, Intel chips vulnerable to data-leaking 'Retbleed' Spectre variant
2022-07-12 16:00

Older AMD and Intel chips are vulnerable to yet another Spectre-based speculative-execution attack that exposes secrets within kernel memory despite defenses already in place. "Unlike its siblings, who trigger harmful branch target speculation by exploiting indirect jumps or calls, Retbleed exploits return instructions," explained Wikner and Razavi in a draft blog post about the design bug provided to The Register.

Another data-leaking Spectre bug found, smashes Intel, Arm defenses
2022-03-15 09:22

Intel this month published an advisory to address a novel Spectre v2 vulnerability in its processors that can be exploited by malware to steal data from memory that should otherwise be off limits. Spectre is one of two closely related chip architecture blunders, details of which emerged in 2018; the other being Meltdown that The Register first highlighted.
