Summary
Improper input validation in the Power Management Firmware (PMFW) of AMD EPYC 9005 Series and EPYC Embedded 9005 Series Processors lets a local attacker with low-privilege access crash the system or cause a denial of service. The attacker needs to be logged in on the machine, and no user action is required.
Written by anthropic/claude-haiku-5.5 from the sources below. Verify against them.
Read the original description
Improper validation of specified quantities in input within AMD Power Management Firmware (PMFW) could allow a local attacker to pass unsanitized input, potentially resulting in a system crash or denial of service.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-0101 (Improper validation of specified quantities in input within AMD Power Management Firmware (PMFW) could allow a local attacker to pass…), using the cve.now data below.
Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.
What cve.now has for CVE-2026-0101 (entry last updated 2026-11-13):
Affected:
- AMD AMD EPYC™ 9005 Series Processors: version range not reported
- AMD AMD EPYC™ Embedded 9005 Series Processors: version range not reported
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-0101 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-0101 only. If you also check another CVE, look up its own KEV status; never assume it from this one.
How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.
Verify against the linked advisories before concluding, and cite the date you read each one:
- https://www.amd.com/en/resources/product-security/bulletin/AMD-SB-3056.html
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.
Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
