The vulnerability of the DTLS component in the OpenSSL library, which allows a hacker to trigger a service failure

The vulnerability of the DTLS component in the OpenSSL library is related to asymmetric resource consumption. Exploiting this vulnerability can allow a malicious actor to cause service failures...

CVE-2026-55776

A flaw was found in OpenBao. An authenticated user with write access to the transit secrets engine could trigger a server crash by creating a key with specific asymmetric key types and a 'derived' parameter set to true. This vulnerability, caused by a double-unlock of a mutex, leads to a denial o...

CVE-2026-55776 OpenBao: Transit secrets engine crashes on key creation with `derived: true` for asymmetric key types

OpenBao is an open source identity-based secrets management system. Prior to 2.5.5, an authenticated OpenBao caller with write access to transit/keys/ could terminate the server process by setting derived to true while the type parameter selected rsa-, ecdsa-, or ed25519. The Transit policy...

Astra Linux – Vulnerability in openssl1.0

In situations where an attacker receives automated notifications of the success or failure of a decryption attempt, an attacker can recover the CMS/PKCS7 transport encryption key after sending a very large number of messages to be decrypted. They can also decrypt any RSA-encrypted message encrypt...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KEYS: prevented NULL pointer dereference in findasymmetrickey. In findasymmetrickey, if all NULL values are passed as arguments to id0,1,2, the kernel will first emit a WARN message, but then there will be an oops because id2 wil...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: crypto: asymmetrickeys – prevented overflow in asymmetrickeygenerateid. Use checkaddoverflow to prevent potential integer overflows when adding the lengths of binary blobs and the size of an asymmetrickeyid structure. Return...

Important: openssl11

Issue Overview: Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a...

The vulnerability of the _get_outline() function in the pypdf/_doc_common.py library of the Python library for working with PDF files, PyPDF, allows a attacker to cause a service failure.

The vulnerability of the getoutline function in the pypdf/doccommon.py library of the Python PDF handling library PyPDF is related to asymmetric resource consumption. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-85394

python-jose through 3.5.0 fails to properly validate asymmetric keys in HMAC initialization, accepting DER-encoded public keys that lack PEM armor or SSH prefixes. Attackers holding the service's public key can forge HS256 tokens that pass verification when algorithms are not explicitly restricte...

CVE-2026-54874

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires.
