In the Linux kernel, the following vulnerability has been resolved: x86/cpu: Avoid running off the end of an AMD erratum table The NULL array terminator at the end of erratum_1386_microcode was removed during the switch from x86_cpu_desc to x86_cpu_id. This causes readers to run off the end of the array. Replace the NULL.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2025-37751 is a high public vulnerability record for Linux Linux. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether Linux Linux is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: Linux Linux f3f3251526739bb975b97f840c56b3054dba8638 <f0df00ebc57f803603f2a2e0df197e51f06fbe90 (f3f3251526739bb975b97f840c56b3054dba8638 <f0df00ebc57f803603f2a2e0df197e51f06fbe90). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.

Security analyst

Signals on file: CVSS 7.1, EPSS 16.0%. It is not currently listed in the CISA Known Exploited catalog. Sources contributing to this record: cve_org, euvd. Public exploit references, when present, are outbound links only and are not proof of active exploitation. This is a catalog interpretation of stored metadata.
