Comment 2 Martin Osvald 🛹 2023-06-22 06:26:18 UTC
Dhcp is not affected by this CVE.

Fixed static overmem_purge() is called by static addrdataset() which is called by exported dns_db_addrdataset() which is never called by dhcp:

[mosvald@fedora dhcp-4.4.3-P1]$ grep --exclude-dir=bind -R dns_db_addrdataset
[mosvald@fedora dhcp-4.4.3-P1]$

Other parts of the upstream patch either fix pieces in addrdataset() or introduce a new expire_lru_headers().

Given the information above, closing this as NOTABUG.
