alexcrichton opened PR #13015 from alexcrichton:fix-oob-flags to bytecodealliance:main:

Note: this is a fix for GHSA-m758-wjhj-p3jq

This commit fixes a panic when a component model Value is lifted from a flags value which specifies out-of-bounds bits as 1. This is specified in the component model to ignore the out-of-bounds bits, which flags! correctly did (and thus bindgen!), but Value treated out-of-bounds bits as a panic due to indexing an array.
