openssl: QUIC server may trigger double free when processing INITIAL packet

A flaw was found in OpenSSL. A malformed INITIAL packet with an invalid DCID destination connection ID can cause the QUIC server to double free the QRX object. This issue leads to memory corruption, causing the termination of the QUIC server process and resulting in a denial of service...

openssl: QUIC ACK-only packet retention can cause memory exhaustion

A flaw was found in OpenSSL. The QUIC protocol implementation retains metadata for ACK-only packets for the lifetime of a connection, leading to excessive memory consumption. This allows a peer to repeatedly send ack-eliciting packets while not acknowledging ACK-only responses to cause memory...

openssl: OpenSSL: Denial of Service via unbounded memory growth in QUIC server

A flaw was found in OpenSSL. A remote attacker could exploit this by sending a large number of QUIC Initial packets to an OpenSSL QUIC server. This can cause the server to allocate and queue new incoming channels without limit, leading to unbounded memory growth. The excessive memory consumption...

Important: bluez

Issue Overview: A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response EIR packet that causes a buffer overflow when the target device performs Bluetooth...

CVE-2026-90558 sngrep through 1.8.4 Stack Buffer Overflow via SIP Headers

sngrep through 1.8.4 contains stack buffer overflow vulnerabilities in SIP attribute formatting routines when header values exceed the 255-byte buffer limit. Attackers can craft malicious SIP packets with oversized Call-ID, X-Call-ID, or other header fields to overflow stack buffers and cause...

EUVD-2026-76739

A deployment mode intended to expose only read access to a bundled packet-analysis component's interface denies a list of write-capable routes by pattern, but the pattern omits routes that modify tags attached to stored session records, and the proxy configuration otherwise permits the request...

EUVD-2026-76742

An example environment-configuration file ships with a fixed, publicly-known secret value used to sign authentication cookies for a bundled packet-analysis component. A deployment that copies this example file into active configuration without running the setup routine that regenerates the value...
