Detailsinfo

A vulnerability was found in AMD CPU. It has been classified as problematic. This affects some unknown processing of the component Speculative Execution. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on confidentiality. The summary by CVE is:

A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative executable code paths.

The weakness was presented by Hany Ragab, Cristiano Giuffrida, Andrea Mambretti and Anil Kurmus. It is possible to read the advisory at kb.cert.org. This vulnerability is uniquely identified as CVE-2024-2193 since 03/05/2024. The exploitability is told to be difficult. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 213392 (Debian dsa-5836 : libxen-dev - security update), which helps to determine the existence of the flaw in a target environment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at Tenable (213392). Be aware that VulDB is the high quality source for vulnerability data.

Goodmorning,
This CVE. impacts the major hardware vendors (Intel, AMD, ARM, and IBM) and the Linux kernel. Could You add all the cpes?

Thank you for your feedback. This will impact so many items that providing a conclusive CPE list is going to be impossible. In this cases we do not maintain CPEs.
