CVE-2026-53921

odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. Prior to version 25.12, odhcpd's DHCPv6 IA response handler writes past the end of a fixed 512-byte stack buffer pdbuf when a single DHCPv6 REQUEST carries enough IA options to nearly exhaust the reply space. Two...

kernel: crypto: af_alg - Cap AEAD AD length to 0x80000000

A flaw was found in the Linux kernel's afalg cryptography module. This vulnerability involves an arithmetic overflow when processing associated data lengths during the transmit buffer size check. A remote attacker could exploit this flaw by providing a specially crafted associated data length,...

CVE-2026-53921

A critical stack-based buffer overflow exists in the odhcpd daemon of OpenWrt , affecting versions prior to 24.10.8 and 25.12.5 . The vulnerability is triggered during the serialization of DHCPv6 Reply packets in the build_ia() and dhcpv6_ia_handle_IAs() functions. When processing a specially cra...
