CVE-2026-5477

An integer overflow existed in the wolfCrypt CMAC implementation, that could be exploited to forge CMAC tags. The function wcCmacUpdate used the guard if cmac-totalSz != 0 to skip XOR-chaining on the first block where digest is all-zeros and the XOR is a no-op. However, totalSz is word32 and wrap...

OESA-2026-2480 lwip security update

lwip is a small independent implementation of the TCP/IP protocol suite. Security Fixes: A vulnerability was found in lwIP up to 2.2.1. Affected is the function snmpparseinboundframe of the file src/apps/snmp/snmpmsg.c of the component snmpv3 USM Handler. Performing a manipulation of the argument...

CVE-2026-45787 electerm's encrypt method not safe enough

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.9.5, deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common...

aiosend: Deserialization of request body before signature verification (Pre-auth DoS) in webhook handler

Summary WebhookHandler.feedupdate deserializes the entire request body before verifying the HMAC signature. This allows an unauthenticated attacker to force expensive parsing of arbitrary JSON payloads that will ultimately be rejected, leading to unnecessary CPU and memory consumption. Severity...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/tcp-ao: The comparison of MACs has been fixed to be at constant time. To prevent timing attacks, MACs need to be compared at constant time. Use the appropriate helper functions for this purpose...

CVE-2026-8836

A vulnerability was found in lwIP up to 2.2.1. Affected is the function snmpparseinboundframe of the file src/apps/snmp/snmpmsg.c of the component snmpv3 USM Handler. Performing a manipulation of the argument msgAuthenticationParameters results in stack-based buffer overflow. The attack may be...

CVE-2026-8836 lwIP snmpv3 USM snmp_msg.c snmp_parse_inbound_frame stack-based overflow

A vulnerability was found in lwIP up to 2.2.1. Affected is the function snmpparseinboundframe of the file src/apps/snmp/snmpmsg.c of the component snmpv3 USM Handler. Performing a manipulation of the argument msgAuthenticationParameters results in stack-based buffer overflow. The attack may be...

Cryptographic Failure

electerm is vulnerable to Cryptographic Failure. The vulnerability is due to the use of deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC for synced bookmark/profile data, which allows an attacker to crack common passwords across installations and perform undetected...

electerm's encrypt method not safe enough

Impact Insecure sync encryption: deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common passwords across installs and perform undetected ciphertext bit-flips to alte...

EUVD-2026-29086

Deserialization of untrusted data CWE-502 in pgAdmin 4 FileBackedSessionManager. The session manager performed unsafe deserialization of session-file contents using Python's standard object-serialization module before performing any HMAC integrity check. Any file dropped into the sessions directo...

CVE-2026-43384

A flaw was found in the Linux kernel's TCP Authentication Option TCP-AO implementation. This vulnerability arises from a non-constant-time comparison of Message Authentication Codes MACs. A remote attacker could potentially exploit this timing discrepancy to perform a timing attack, which may lea...

CVE-2026-43383

A flaw was found in the Linux kernel's TCP MD5 signature option. This vulnerability allows a remote attacker to perform timing attacks due to a non-constant-time comparison of Message Authentication Codes MACs. By observing the time taken for MAC comparisons, an attacker could potentially infer...
