openssl: AES-OCB IV Ignored on EVP_Cipher() Path

A flaw was found in OpenSSL. Applications that use the AES-OCB encryption method with a specific one-shot interface EVPCipher will have their provided Initialization Vector IV silently discarded. This leads to the same internal cryptographic value being used repeatedly, which compromises the...

PT-2026-90520

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...

CVE-2026-81019

wolfProvider before 1.2.2 generates the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increments it per record. As a result every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. Reusing a GCM key and nonce...

CVE-2026-81019 wolfProvider reuses the AES-GCM nonce on every TLS 1.2 / DTLS 1.2 record

wolfProvider before 1.2.2 generates the 8-byte explicit AES-GCM nonce once when the TLS write key is set and never increments it per record. As a result every TLS 1.2 and DTLS 1.2 AES-GCM record within a connection is encrypted under an identical key and nonce pair. Reusing a GCM key and nonce...

Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value enabling MAC forgery, in the IESEngine class when initialized through the 4-argument init without a block cipher, where the KDF is seeded only from the ECDH shared secret and split into a...

CVE-2026-50722

Libreswan, via the function RSAauthenticatehashsignaturepkcs115rsa, did not correctly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v15 RFC 8017. A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload...

SUSE-SU-2026:22132-1 Security update for openssl-3

This update for openssl-3 fixes the following issues - CVE-2024-41996: DHEATATTACK: Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers to trigger expensive server-side DHE bsc1230698. - CVE-2026-7383:...

EUVD-2026-35489

Issue summary: When an application drives an AES-OCB context through the public EVPCipher one-shot interface, the application-supplied initialisation vector IV is silently discarded. Impact summary: Every message encrypted under the same key uses the same effective nonce regardless of the IV...

CVE-2026-45446 Incorrect Tag Processing for Empty Messages in AES-GCM-SIV and AES-SIV modes

Issue summary: The implementations of AES-SIV RFC 5297 and AES-GCM-SIV RFC 8452 mishandle the authentication of AAD Additional Authenticated Data with an empty ciphertext allowing a forgery of such messages. Impact summary: An attacker can forge empty messages with arbitrary AAD to the victim's...

PT-2026-47843

Name of the Vulnerable Software and Affected Versions OpenSSL versions 3.0 through 3.3 Description The implementations of AES-SIV and AES-GCM-SIV mishandle the authentication of Additional Authenticated Data AAD when the ciphertext is empty, which allows for the forgery of such messages. In the...

PT-2026-47842

Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description When using the AES-OCB cipher with the one-shot EVP Cipher interface, the application-supplied initialisation vector IV is silently discarded. This causes every message encrypted with the sam...

CVE-2026-50226

CVE-2026-50226 affects the AcerConnect OTA application. The issue arises from fixed AES-128-CBC keys inside the app, allowing attackers to forge authorization credentials for arbitrary IMEI numbers. This enables unauthorized actors to list catalog items and extract protected binaries from pre-sig...

Nginx-UI Settings API Exposes Protected Secrets

The GetSettings API handler api/settings/settings.go:24-65 serializes all settings structs to JSON and returns them to authenticated users. Many sensitive fields are tagged with protected:"true" - however, this tag is only enforced during writes via ProtectedFill in SaveSettings and is completely...

Nutanix AHV : Multiple Vulnerabilities (NXSA-AHV-10.0.0.1)

The version of AHV installed on the remote host is prior to 10.0.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-10.0.0.1 advisory. - RADIUS Protocol under RFC 2865 is susceptible to forgery attacks by a local attacker who can modify any valid Response...

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...

PT-2026-28474
