CVE-2026-48045

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.12, AsyncListener.handlequeryordefer retained every truncated TC-bit incoming query, each up to MAXMSGABSOLUTE = 8966 bytes, in self.deferredaddr and armed a per-address timer in self.timersaddr without...

CVE-2026-47180

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.5, DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer, and a single mDNS packet carrying chained pointers can trigger a RecursionError that escapes DNSIncoming.init, causing...

UBUNTU-CVE-2026-47184

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.7, DNSCache.asyncadd inserted every response record into cache, expirations, expireheap, and servicecache without a cap, allowing unauthenticated hosts on the local link over UDP/5353 224.0.0.251 / ff02::f...

CVE-2026-47183

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.6, DNSIncoming.logexceptiondebug and the four QuietLogger exception-dedup methods stored an unbounded seenlogs dictionary keyed by attacker-influenced IncomingDecodeError messages, retaining sys.excinfo...

CVE-2026-48487

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.16, readcharacterstring and readstring in src/zeroconf/protocol/incoming.py advanced self.offset by attacker-declared RDLENGTH without checking it against self.datalen, allowing unauthenticated hosts on th...

CVE-2026-47184 Zeroconf: Unbounded DNS record cache allows LAN-local memory exhaustion via multicast flood

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.7, DNSCache.asyncadd inserted every response record into cache, expirations, expireheap, and servicecache without a cap, allowing unauthenticated hosts on the local link over UDP/5353 224.0.0.251 / ff02::f...

CVE-2021-27137

An issue was discovered in router/upnp/src/ssdp.c in DD-WRT before 45724. An unsafe strcpy in the UPnP handling functionality allows an unauthenticated remote attacker to send a request that would overflow an internal fixed buffer. Exploitation requires the DD-WRT user to enable UPnP which is off...

Devolutions Server 2026.2.4 <= 2026.2.7 Credential Exposure (DEVO-2026-0020)

The version of Devolutions Server installed on the remote host is 2026.2.4 through 2026.2.7. It is, therefore, affected by a vulnerability: - Improper input validation in the PAM AD discovery endpoints allows an authenticated user with the UserGroupsView permission to coerce server-side...

CVE-2026-10651

The CVE-2026-10651 affects Zephyr’s Bluetooth Classic SDP parser (subsys/bluetooth/host/classic/sdp.c) where bt_sdp_parse_attribute() reads a 3-byte attribute (1-byte type, 2-byte id) but then unconditionally pulls an extra value type byte without verifying remaining length. A truncated 3-byte at...

CVE-2026-10651 Bluetooth Classic SDP parser truncation bug in bt_sdp_parse_attribute() leads to reachable assertion and possible out-of-bounds read

A malformed Bluetooth Classic SDP attribute can trigger a reachable assertion in Zephyr's SDP parser. In subsys/bluetooth/host/classic/sdp.c, btsdpparseattribute accepts an input buffer once it contains the 1-byte attribute type and 2-byte attribute id, but then unconditionally pulls an additiona...
