CVE-2022-23824

Summary: CVE-2022-23824 is listed as a Xen-related vulnerability in Debian security advisories and Gentoo GLSA, indicating multiple vulnerabilities in the Xen hypervisor that could lead to privilege escalation, denial of service, or information leaks. The Debian entry explicitly groups CVE-2022-2...

CVE-2022-27672

CVE-2022-27672 describes a local information disclosure vulnerability on certain AMD CPUs where, when SMT is enabled, the processor may speculatively execute instructions using a target from the sibling thread after an SMT mode switch. The underlying issue is tied to speculative execution across ...

CVE-2022-23823

CVE-2022-23823 describes a timing-attack information disclosure risk on AMD processors with DVFS. Connected sources show F5 advisories (K43357358) tying Hertzbleed to BIG-IP on AMD CPUs, listing affected BIG-IP branches (e.g., 17.x up to 17.5.03) with “Will not fix” for some lines, and provide a ...

CVE-2022-23821

CVE-2022-23821 describes an improper access control in AMD System Management Mode (SMM) that could allow an attacker to write to SPI ROM and potentially achieve arbitrary code execution. Connected sources indicate this affects AMD ASP/SMM components and is mitigated by Platform Initialization (PI...

CVE-2023-4969

CVE-2023-4969 describes a vulnerability where a GPU kernel can read sensitive data from another GPU kernel through the local memory region across various architectures. The issue is a confidentiality exposure (HIGH) with LOCAL access and LOW attack complexity; no user interaction is required. The...

CVE-2023-20579

CVE-2023-20579 involves improper access control in the AMD SPI protection feature. A local Ring0 (kernel mode) user could bypass protections, potentially affecting integrity and availability. Connected documents confirm this is an AMD SPI protection flaw and cite multiple advisories (NVD, Red Hat...

CVE-2023-20555

CVE-2023-20555 is an AMD SMM memory corruption flaw due to insufficient input validation in CpmDisplayFeatureSmm, allowing an attacker to overwrite an arbitrary bit in an attacker-controlled pointer and potentially execute code in SMM. Connected sources indicate this affects AMD processors with S...

CVE-2022-23820

CVE-2022-23820 corresponds to a vulnerability in AMD ASP/PSP/SMM handling where failure to validate the AMD SMM communication buffer could allow an attacker to corrupt SMRAM and achieve arbitrary code execution. Public details in AMD’s bulletin AMD-SB-5001 confirm the issue and map it to multiple...

CVE-2021-46778

CVE-2021-46778 describes an information-disclosure side-channel vulnerability in AMD CPUs with SMT (Zen 1–Zen 4). The root cause is execution unit scheduler contention on SMT-enabled cores, allowing an attacker to infer data by measuring scheduler-queue contention. Public documents identify affec...

CVE-2021-46758

CVE-2021-46758 involves insufficient validation of SPI flash addresses in the AMD Secure Processor (ASP) bootloader. The issue may allow an attacker to read data mapped beyond SPI flash, potentially impacting availability and integrity. Related documents confirm the vulnerability in ASP bootloade...
