CVE-2026-54873

A flaw in OpenSSL allows a remote attacker to cause a Denial of Service (DoS) by sending specially crafted network packets to a QUIC protocol endpoint. The vulnerability occurs because the QUIC stack retains memory in packet buffers until the receiving application copies the stream data, a design...

CVE-2026-97602

A flaw was found in the Linux kernel. During network namespace cleanup, incomplete packet fragmentation queues are flushed without properly updating their completion state. A local attacker with access to unprivileged network namespaces can exploit this race condition during IPv6 packet reassembl...

CVE-2026-96422

CVE-2026-102715: Out-of-bounds Write

Any host on the LAN can send two mDNS records and make the responder write past the end of its transmit packet. The string table stores each name in a slot rounded up to a multiple of four: c / addons/mdns/nxdmdns.c:11436, 11443, 11447 / memorylen = memorylen & 0xFFFFFFFC + 8 & 0xFFFFFFFF; ... le...

CVE-2026-102721: Out-of-bounds Read

A TFTP server that answers with a short ERROR packet makes the client read up to 64 bytes past the received datagram. Each receive path checks only that the datagram is at least four bytes long nxdtftpclient.c:1229, 1521, 1984. When the opcode is NXTFTPCODEERROR the message string is copied with ...
