Integer underflow in wolfSSL packet sniffer = 5.9.0 allows an attacker to cause a program crash in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by sslDecodePacket. The underflow wraps a 16-bit length to a large valu...

CVE-2026-51807

Heap-based out-of-bounds write in j2kprecinctsubband::parsepacketheader in OpenHTJ2K versions 0.18.3 and earlier fixed in v0.18.4 caused by missing bounds validation before coding-pass lengths are written to j2kcodeblock::passlength128. A crafted JPEG 2000 codestream containing malformed PPM pack...

CVE-2026-51807

OpenHTJ2K is affected by a Buffer Overflow vulnerability in versions prior to 0.18.5 due to a flaw in j2k_precinct_subband::parse_packet_header() within source/core/coding/coding_units.cpp. Exploitation could allow an attacker to execute arbitrary code. A fix exists in newer releases (e.g., 0.18....

kernel: Linux kernel: Memory leak in networking due to incorrect GRO packet handling

A flaw was found in the Linux kernel's networking component. Incorrect memory accounting when handling Generic Receive Offload GRO packets can lead to a persistent memory leak. This occurs because the system incorrectly tracks memory usage for network packets, preventing proper cleanup of network...

kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result

A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...

CVE-2026-10665

CVE-2026-10665 concerns Zephyr’s WireGuard implementation (subsys/net/lib/wireguard). The flaw: wg_process_data_message() linearizes an inbound payload into a fixed pool buffer, passing the attacker-controlled data_len as both the destination capacity and copy length to net_buf_linearize, ignorin...
