Created llvm tracking bugs for this issue:

Affects: fedora-all [bug 2225616]

Comment 3 Siddhesh Poyarekar 2023-07-25 15:41:01 UTC

What's the security rationale for this?  If the upstream LLVM security group has agreed on the security impact then this document should be updated to refect that:

https://llvm.org/docs/Security.html#what-is-considered-a-security-issue

because at the moment it states that there are no security-sensitive parts in LLVM.  I couldn't track an upstream discussion about this either.  Likewise for CVE-2023-29933, CVE-2023-29934, CVE-2023-29935, CVE-2023-29941 and CVE-2023-29942.
