Four Novel Cross-Domain Leaks Detected
4 NEW LEAKS IDENTIFIEDOur comprehensive testing campaign identified critical, previously unknown microarchitectural vulnerabilities across diverse CPU architectures.
Cross-VM Leakage on AMD Zen 4 (CVE-2024-36357)
A novel microarchitectural effect allows an attacker VM to infer cached memory bits from another VM. This vulnerability highlights the need for constant vigilance in cloud environments.
Summary: An attacker VM can infer any bit from the memory of another VM, provided the victim VM has previously accessed it. This could allow reading arbitrary memory ranges. This leak has been assigned CVE-2024-36357 with potential high security impact.
Kernel-to-User Leakage on AMD Zen 4 (CVE-2024-36350)
A user process can observe recently-stored values from kernel mode, enabling extraction of privileged data. This finding underscores the challenges in protecting kernel boundaries.
Summary: A user-level gadget demonstrates timing dependency on data stored in kernel mode, allowing an unprivileged attacker to extract privileged data. This is assigned CVE-2024-36350 with moderate-to-high impact.
Rogue Read of RDTSCP-AUX (CVE-2024-36349)
Speculative reading of the auxiliary timestamp counter register, even when architecturally disabled, affects Intel and AMD CPUs, contradicting vendor claims.
Summary: Speculative execution allows user processes to read the auxiliary timestamp counter (RDTSCP AUX) even when disabled, affecting Intel and AMD CPUs. This contradicts AMD's claims and is assigned CVE-2024-36349. Impact is considered low.
