Attack Vector: Local
Attack Complexity: High
Privileges Required: Low
User Interaction: None
Scope: Changed
Confidentiality: High
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

To mitigate CVE-2024-36357, European organizations should take the following specific actions: 1) Monitor AMD and OS vendors for microcode and software patches addressing this vulnerability and apply them promptly once released. 2) Implement strict access controls to limit local access to systems running AMD EPYC 7003 processors, including enhanced authentication and monitoring of privileged accounts. 3) Employ virtualization and containerization best practices to isolate workloads and reduce cross-tenant data leakage risks. 4) Use hardware-assisted security features such as AMD SEV (Secure Encrypted Virtualization) where applicable to protect VM memory confidentiality. 5) Conduct regular security audits and side-channel attack detection mechanisms to identify anomalous behavior indicative of exploitation attempts. 6) Educate system administrators and security teams about transient execution risks and ensure incident response plans include scenarios involving microarchitectural attacks. 7) Where feasible, segregate sensitive workloads onto hardware platforms not affected by this vulnerability until mitigations are fully deployed. These targeted measures go beyond generic advice by focusing on local access restrictions, workload isolation, and proactive patch management specific to AMD EPYC 7003 processors.

Description

A transient execution vulnerability in some AMD processors may allow an attacker to infer data in the L1D cache, potentially resulting in the leakage of sensitive information across privileged boundaries.

Impact

For European organizations, the primary impact of CVE-2024-36357 lies in the potential leakage of sensitive information across privilege boundaries within systems using AMD EPYC 7003 processors. This can compromise confidentiality of data processed in multi-tenant environments such as cloud platforms, virtualized servers, and high-performance computing clusters. The vulnerability could enable attackers with local access to extract cryptographic keys, passwords, or other sensitive data from co-resident processes or virtual machines. Although the attack complexity is high and requires local access, insider threats or compromised accounts could exploit this vulnerability. The lack of impact on integrity and availability reduces the risk of direct system disruption or data manipulation. However, the confidentiality breach could lead to regulatory compliance issues under GDPR and damage to organizational reputation. European cloud providers and enterprises relying on AMD EPYC 7003 CPUs for critical workloads must consider this vulnerability in their risk assessments and incident response planning.

CWE-1421Exposure of Sensitive Information in Shared Microarchitectural Structures during Transient Execution (opens in a new tab)
Base weakness
A processor event may allow transient operations to access architecturally restricted data (for example, in another address space) in a shared microarchitectural structure (for example, a CPU cache), potentially exposing the data over a covert channel.
Architecture and Design
Hardware designers may choose to engineer the processor's pipeline to prevent architecturally restricted data from being used by operations that can execute transiently.
Architecture and Design
Hardware designers may choose not to share microarchitectural resources that can contain sensitive data, such as fill buffers and store buffers.
Architecture and Design
Hardware designers may choose to sanitize specific microarchitectural state (for example, store buffers) when the processor transitions to a different context, such as whenever a system call is invoked.
