CVE-2025-40202

HIGHPre-NVD 7.87.8
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.8 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 92% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

In the Linux kernel, the following vulnerability has been resolved:

ipmi: Rework user message limit handling

The limit on the number of user messages had a number of issues, improper counting in some cases and a use after free.

Restructure how this is all done to handle more in the receive message allocation routine, so all refcouting and user message limit counts are done in that routine. It's a lot cleaner and safer.
