EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 99% 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).

A fix is available — apply it.

Vim is an open source, command line text editor. Prior to 9.2.0841, prop_add_one() in src/textprop.c uses the proplen value from get_text_props() to increment a uint16_t property count beyond 0xffff, wrapping the count to zero and copying existing text-property records into a heap allocation sized for none of them. This issue is fixed in version 9.2.0841.
