Answer in brief
CVE-2026-40393 records a High severity (CVSS 8.1) vulnerability in CISA ADP Vulnrichment. The current sources do not mark it as known exploited. The current feed maps mesa3d/Mesa (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 8.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In Mesa before 25.3.6 and 26 before 26.0.1, out-of-bounds memory access can occur in WebGPU because the amount of to-be-allocated data depends on an untrusted party, and is then used for alloca.
