PT-2026-67530

python-cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 49.0.0, when resolving invalid certificate chains that include duplicate copies of self-signed certificates, the processing recursively invokes the same candidate, leading to an...

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...

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...

EUVD-2026-50614

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...

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...
