CVE-2026-69248: Improper Certificate Validation

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In versions 45.0.0 through 48.0.0, if an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com,...

Name of the Vulnerable Software and Affected Versions cryptography versions prior to 49.0.0 Description A flaw exists in the verifier where a wildcard pattern in the DNS Subject Alternative Name SAN of a leaf certificate is incorrectly treated as matching a more-specific permitted constraint of a...

CVE-2026-69247: Observable Timing Discrepancy

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 44.0.0 until 50.0.0, pkcs7decryptder, pkcs7decryptpem, and pkcs7decryptsmime reported the outcome of decrypting a RecipientInfo's encryptedKey in several distinguishable ways, one of which...

CVE-2026-10774 PSA key-slot leak in Bluetooth Mesh subnet deletion leading to resource-exhaustion DoS

Zephyr's Bluetooth Mesh subnet key management leaks one PSA Crypto key slot on every subnet-key teardown. In subsys/bluetooth/mesh/subnet.c, netkeyscreate imports the Private Beacon Key into a PSA key slot under CONFIGBTMESHPRIVBEACONS enabled by default, but subnetkeysdestroy guarded the matchin...

CVE-2026-10774

Summary. CVE-2026-10774 affects Zephyr’s Bluetooth Mesh implementation. The vulnerability arises when subnet keys are torn down: net_keys_create() imports the Private Beacon Key into a PSA key slot, but subnet_keys_destroy() did not balancedly free the slot due to a removed Kconfig guard. This cr...

CVE-2026-67336: Use of a Broken or Risky Cryptographic Algorithm

better-auth versions before 1.6.11 contain insecure cryptographic defaults in the oidcProvider and mcp plugins that advertise the none algorithm and accept plain PKCE by default. Attackers can exploit algorithm negotiation to accept unsigned tokens or intercept authorization codes when PKCE plain...

SUSE CVE-2026-64620

FreeRDP before 3.28.0 affected outlength, so out-of-bounds bytes are written before the bounds check. On the server side, when a client selects RDP Standard Security, the encrypted client random is decrypted into a fixed 32-byte buffer. Because the server publishes its RSA public key, an...

Bouncy Castle Java FIPS DoS

The vulnerability of Java Cryptographic Libraries, specifically Bouncy Castle for Java FIPS and Bouncy Castle for Java LTS, is related to an uncontrolled resource consumption. Exploiting this vulnerability can allow attackers to cause service failures...

Mind the Gap: Policy Vs Reality in Post-Quantum TLS Deployment

Post-quantum cryptography PQC has evolved from a long-term planning concern into an operational priority. Following NIST's standardization of PQC, governments and standard bodies published transition roadmaps outlining migration timelines, priority sectors, and deployment strategies. However, our...

PT-2026-67530

Name of the Vulnerable Software and Affected Versions python-cryptography versions prior to 49.0.0 Description When resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an exponential...

kernel: crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id

In the Linux kernel, the following vulnerability has been resolved: crypto: asymmetrickeys - prevent overflow in asymmetrickeygenerateid Use checkaddoverflow to guard against potential integer overflows when adding the binary blob lengths and the size of an asymmetrickeyid structure and return...

CVE-2026-64313

A flaw was found in the Linux kernel's Elliptic Curve Cryptography ECC component. An attacker on an adjacent network could exploit an error in the very long integer vli multiplication's carry flag calculation. This mathematical inaccuracy in cryptographic operations could lead to high impact on...

CVE-2026-64310

A flaw was found in the Linux kernel's crypto: ccp component. A local user, by triggering specific SEV Secure Encrypted Virtualization input/output control ioctl operations when SEV initialization fails and Kernel-based Virtual Machine KVM is actively running virtual machines, could cause the...

Inappropriate implementation in Crypto in Google Chrome on Mac prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. Chromium security severity: Medium...

Formalization of Security

Proof assistants are often used to validate that designs and implementations meet their expected security properties. A further motivation for using proof assistants is to support certification. This chapter focuses on their applications to system security, language-based security, secure...

Distributed Point Functions and Function Secret Sharing

A distributed point function DPF is a cryptographic primitive that enables compressed additive sharing of a secret weight-1 vector equivalently, a point function across two or more parties. The appealing lightweight structure of DPF constructions has enabled a wide range of applications. These...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...
