Epyc 7643 vulnerabilitiesRanked by how likely they are to be used.
Epyc 7643 is made by Amd. We track 95 published vulnerabilities listed under that exact name, across 0 versions. None of them is on the list of flaws known to be exploited today. Amd lists newer releases under their own names, such as Epyc 7643 Firmware, so check those pages too.
We keep watching the known-exploited list.
Is Epyc 7643 listed under other names? Yes.
Amd also lists Epyc 7643 under more specific names, such as Epyc 7643 Firmware. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.
Which Epyc 7643 vulnerabilities are being exploited?
This is the list that matters most: flaws criminals are using now.
None of Epyc 7643's published vulnerabilities is on the list of flaws known to be exploited today. We keep watching that list.
Which Epyc 7643 flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.
- 7.3%CVE-2023-20569Medium
A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction.
- 1.7%CVE-2020-12967High
The lack of nested page table protection in the AMD SEV/SEV-ES feature could potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to compromise the server hypervisor.
- 1.7%CVE-2021-26311High
In the AMD SEV/SEV-ES feature, memory can be rearranged in the guest address space that is not detected by the attestation mechanism which could be used by a malicious hypervisor to potentially lead to arbitrary code...
- 1.0%CVE-2021-26322High
Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”.
- 1.0%CVE-2020-12988High
A potential denial of service (DoS) vulnerability exists in the integrated chipset that may allow a malicious attacker to hang the system when it is rebooted.
- 1.0%CVE-2023-20592Medium
Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest...
- 0.9%CVE-2021-26338High
Improper access controls in System Management Unit (SMU) may allow for an attacker to override performance control tables located in DRAM resulting in a potential lack of system resources.
- 0.8%CVE-2023-20575Medium
A potential power side-channel vulnerability in some AMD processors may allow an authenticated attacker to use the power reporting functionality to monitor a program’s execution inside an AMD SEV VM potentially...
- 0.8%CVE-2023-20520Critical
Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution.
- 0.8%CVE-2021-46769High
Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to execute arbitrary DMA copies, which can lead to code execution.
