{"affected":[{"product":"esp-protocols","source":"CNA: GitHub_M","vendor":"espressif","versions":[{"status":"affected","version":"< 1.11.2"}]}],"cveId":"CVE-2026-64860","cwes":["CWE-400","CWE-674"],"description":"ESP-Protocols is a collection of protocol components for ESP-IDF. Prior to mDNS version 1.11.2, the `mdns` component follows DNS name-compression pointers recursively when parsing fully qualified domain names (FQDNs) in inbound mDNS packets without capping pointer-follow depth in `mdns_utils_read_fqdn()`. An unauthenticated attacker on the same link-local network can send a crafted packet to UDP port 5353 on an `ESP-IDF` device using `espressif/mdns` with mDNS enabled. Deep recursion exhausts the fixed-size stack of the mDNS FreeRTOS task, causing a controlled panic and reboot; persistent malicious traffic can cause a crash loop. No confidentiality or integrity impact has been demonstrated, and remote code execution is not claimed. This issue is fixed in mDNS version 1.11.2.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.5,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793887868672,"publishedAt":1793887868672,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/espressif/esp-protocols/security/advisories/GHSA-7fpr-vjw5-2c86"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/espressif/esp-protocols/commit/95c882c7d7d661d28d4685bd052b024154a8402f"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/espressif/esp-protocols/releases/tag/mdns-v1.11.2"}],"remediation":[],"revision":"8824e11f29cf0bddbcc7a5992e71b8df84cbc8c2ed2433e0d2075cd8ab3ba283","sources":[{"modifiedAt":1793887868672,"name":"CNA: GitHub_M","retrievedAt":1793891463009,"url":"https://www.cve.org/CVERecord?id=CVE-2026-64860"}],"ssvc":null,"status":"published","title":"espressif/mdns has Uncontrolled Recursion in mDNS Name Decompression","updatedAt":1793891463009}
