EEF-CVE-2026-54887 DTLS server cookie bypass during startup window due to empty initial cookie secret

Summary Use of Default Cryptographic Key vulnerability in Erlang/OTP ssl DTLS server allows predictable DTLS cookie computation during the startup window, enabling source address verification bypass. On DTLS server startup, dtls\server\connection:initial\hello/3 initializes previous\cookie\secret...

curl: libcurl: curl/libcurl: Remote denial of service via QUIC UDP receive function vulnerability

A flaw was found in curl and libcurl. A malicious HTTP/3 server can exploit an issue in the QUIC UDP receive function by continuously streaming empty UDP datagrams. This can lead to a remote denial of service DoS against a curl or libcurl client, as the helper function discards zero-length UDP...

kernel: ipv4: account for fraggap on the paged allocation path

A flaw was found in the Linux kernel's handling of IPv4 network packets. An error in how the kernel accounts for fragmented data during memory allocation can lead to an undersized memory buffer. This memory handling issue could potentially be exploited by a remote attacker to cause a system crash...

netty-codec-haproxy: Netty HAProxy PROXY protocol v2 codec: Denial of Service via memory leak from crafted PROXY protocol headers

A flaw was found in the Netty HAProxy PROXY protocol v2 codec. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy PROXY protocol v2 header with nested PP2TYPESSL type-length-value TLV records. This can lead to a memory leak, causing the underlying cumulation...

The vulnerability of the library for working with the Protocol Buffers protocol protobufjs, related to uncontrolled changes to object prototype attributes, allows a hacker to trigger a service failure.

The vulnerability of the library for working with the Protocol Buffers protocol Protobuf protobufjs is related to uncontrolled changes to object prototype attributes. Exploiting this vulnerability could allow a malicious actor to cause service failures...

The vulnerability of the decoder in the UTF-8 library for working with the Protocol Buffers protocol (Protobuf) protobufjs allows attackers to bypass existing security mechanisms.

The vulnerability of the UTF-8 decoder in the Protocol Buffers Protobuf protobufjs library is related to incorrect handling of Unicode characters. Exploiting this vulnerability can allow a malicious actor to bypass existing security mechanisms remotely...
