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...

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...

Improper Verification of Cryptographic Signature

Overview PyJWT is a Python implementation of RFC 7519. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via ispemformat in jwt/utils.py, which fails to recognize certain loader-accepted PEM formatting variants as valid PEM. The fix for...

DEBIAN-CVE-2026-102271

PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes HMAC and asymmetric algorithms and...

CVE-2026-102268

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, ispemformat in jwt/utils.py is affected because ispemformat does not recognize every PEM representation accepted by the cryptography loader. This occurs when an application mixes HMAC and asymmetric algorithms and...

CVE-2026-102271

PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes HMAC and asymmetric algorithms and...

CVE-2026-102268 PyJWT: Asymmetric-PEM detection bypass: whitespace/line-ending-mutated public keys skip the HS/asymmetric confusion guard

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, ispemformat in jwt/utils.py is affected because ispemformat does not recognize every PEM representation accepted by the cryptography loader. This occurs when an application mixes HMAC and asymmetric algorithms and...

PT-2026-108340

PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWT HMACAlgorithm.prepare key is affected because HMAC key guard only recognizes top-level public JWK forms and misses container representations. This occurs when an application allows HMAC and asymmetric...

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...

PT-2026-102364

Name of the Vulnerable Software and Affected Versions PyJWT versions 2.13.0 through 2.13.x Description An issue exists in the HMACAlgorithm.prepare key function within jwt/algorithms.py where the raw-JWK detector fails to normalize Unicode byte-order marks BOM before JSON validation. When a publi...

CVE-2026-18754 Hardcoded Cryptographic Key on GV-AS1620 Controller Firmware (GV-Cloud)

The product firmware contains an embedded, static RSA private key utilized by the Lighttpd web server for TLS termination. Exposure of this private key allows malicious actors to breach the confidentiality and integrity of HTTPS communications, enabling traffic decryption and server spoofing...

m2crypto Bleichenbacher timing attack - incomplete fix for CVE-2020-25657

A flaw was found in m2crypto. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data...

gnutls: gnutls: Information disclosure via heap overread in RSA key exchange

A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure...

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

On OpenBao 2.5.4 and 2.5.2and likely earlier versions also, an authenticated caller with write access to transit/keys/ can crash the OpenBao server by issuing a single key-creation request that combines an asymmetric type rsa-, ecdsa-, ed25519 with derived: true. The server returns no HTTP respon...

PT-2026-51111

Name of the Vulnerable Software and Affected Versions OpenBao versions 2.5.2 through 2.5.4 Description An authenticated user with write access to the transit/keys/ endpoint can cause a denial-of-service by crashing the server. This occurs when a key-creation request is sent combining an asymmetri...
