zeroconf has unbounded DNS record cache that allows LAN-local memory exhaustion via multicast flood
Impact DNSCache.asyncadd inserted every response record into cache, expirations, expireheap, and servicecache with no cap on entry count. The only pre-existing protection was a PTR TTL floor DNSPTRMINTTL = 1125 s, RFC 6762 §10, which actually prolonged attacker-injected records, and a periodic...

CVE-2026-42960
NLnet Labs Unbound up to and including version 1.25.0 is vulnerable to poisoning via promiscuous records for the authority section. Promiscuous RRSets that complement DNS replies in the authority section can be used to trick Unbound to cache such records. If an adversary is able to attach such...
dnsmasq: dnsmasq: heap buffer overflow in cache via NAME_ESCAPE expansion
A heap buffer overflow was discovered in dnsmasq's DNS cache. When processing DNS responses, dnsmasq expands certain characters into longer escape sequences, but the cache buffer is not sized to hold the expanded result. A specially crafted DNS response can overflow this buffer, potentially...
