CVE-2026-46433 lldpd: Heap OOB Read in VLAN Decapsulation memmove
lldpd is an implementation of IEEE 802.1ab LLDP. Prior to version 1.0.22, lldpddecode in src/daemon/lldpd.c strips 802.1Q VLAN tags from received Ethernet frames by calling memmove to shift the frame payload 4 bytes left. The third argument byte count is s - 2 ETHERADDRLEN but should be s - 2...

CVE-2026-7473
CVE-2026-7473 affects Arista EOS devices where a tunnel decapsulation config (VXLAN, decap-groups, GRE) can cause the switch to decapsulate and forward unintended tunneled packets whose destination matches the decap IP. Root cause: lack of verification of the tunnel protocol type leading to proce...

libcoap 安全漏洞
Libcoap is a lightweight application protocol implementation developed by ObgM. Libcoap has a security vulnerability, which stems from out-of-bounds read operations during the CBOR decapsulation processing in OSCORE Appendix B.2. This vulnerability may lead to a heap buffer overflow attack throug...
CVE-2026-28815
A remote attacker can supply a short X-Wing HPKE encapsulated key and trigger an out-of-bounds read in the C decapsulation path, potentially causing a crash or memory disclosure depending on runtime protections. This issue is fixed in swift-crypto version 4.3.1...
GHSA-9M44-RR2W-PPP7 Swift Crypto: X-Wing HPKE Decapsulation Accepts Malformed Ciphertext Length
Summary The X-Wing decapsulation path accepts attacker-controlled encapsulated ciphertext bytes without enforcing the required fixed ciphertext length. The decapsulation call is forwarded into a C API, which expects a compile-time fixed-size ciphertext buffer of 1120 bytes. This creates an FFI...
