Summary
# Subword division operations may produce incorrect results
Arithmetic operations may produce incorrect results when compiled with optimizations. For the most part, this bug only causes availability and data integrity issues. However, in some circumstances, it may result in other, more complicated security related flaws, such as buffer overflow conditions.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
