"SLAM Attack Threatens Future Intel, AMD, and Arm CPUs"

Researchers have discovered a new side-channel attack called SLAM that can exploit vulnerabilities in future Intel, Arm, and AMD chips. SLAM targets the newer CPUs' paging method and can mine information from kernel memory, potentially accessing sensitive data like root passwords. While chip makers claim their systems have enough protection against SLAM, it is the first transient execution attack targeting future CPUs, and the effectiveness of their security measures remains uncertain. Intel's Linear Address Masking (LAM), AMD's Upper Address Ignore (UAI), and Arm's TBI are among the security features that SLAM can bypass.

SLAM Attack: A Major Security Flaw Threatens Intel, AMD, and Arm CPUs

Researchers have discovered a new side-channel attack called SLAM that exploits a feature in Intel CPUs called Linear Address Masking (LAM), as well as similar features in AMD and Arm CPUs. SLAM allows an attacker to leak sensitive information from kernel memory, including the root password hash. The attack increases the Spectre attack surface and impacts current and future CPUs from Intel, AMD, and Arm. AMD and Intel are working on mitigations, while Arm states that its systems already mitigate against Spectre v2. Linux maintainers have developed patches to disable LAM by default.
