SUSE CVE-2026-80212

An issue was discovered in the resolv gem before 0.7.2 for Ruby. Resolv::DNS::Resource.getclass, Resolv::DNS::Resource::Generic.create, and Resolv::DNS::SvcParam::Generic.create generate a new class for each unknown DNS resource record type, class pair, or each unknown SvcParamKey, encountered...

resolv: resolv gem: Denial of Service via uncontrolled memory growth from crafted DNS responses

A flaw was found in the resolv gem. An attacker controlling DNS responses e.g., a spoofed response or a malicious upstream DNS server can exploit this by sending crafted DNS responses containing many distinct unknown DNS resource record pairs or SvcParamKeys. This leads to uncontrolled memory...

CVE-2026-69186

A flaw was found in c-ares, an asynchronous resolver library. A remote attacker can send a specially crafted DNS response that causes the aresdnsparse function to trust attacker-controlled record counts without validating if the response contains enough bytes for the claimed records. This can lea...
