crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries

A flaw was found in the crypto/x509 package of golang. This vulnerability allows a remote attacker to cause a Denial of Service DoS by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name SAN entries. The certificate verification process, specifical...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

CVE-2026-80565

In the Linux kernel, the following vulnerability has been resolved: crypto: qce - fix error path in devmqceregisteralgs If ops-registeralgs fails, the error path repeatedly calls the same ops-unregisteralgs from the failed registration. Use the loop index to unregister the previously registered...

CVE-2026-80543

In the Linux kernel, the following vulnerability has been resolved: s390/zcrypt: Pad trailing CCA or EP11 message with zeros The both functions xcrbmsgtotype6cprbmsgx and xcrbmsgtotype6ep11cprbmsgx copy the user space message into a kernel buffer based on the message length. But on further...

CVE-2026-80519

In the Linux kernel, the following vulnerability has been resolved: ovpn: finish crypto callback cleanup before peer release Crypto completion callbacks hold both key-slot and peer references. The peer reference pins the netdev, and dropping the last peer reference can let netdev unregistration a...

CVE-2026-80520

In the Linux kernel, the following vulnerability has been resolved: ovpn: fix NULL dereference when killing missing key ovpncryptokillkey assumes both crypto slots are populated and dereferences each slot before checking it. That is not guaranteed: a peer can have only one installed key, and the...

CVE-2026-80565

This Linux kernel vulnerability affects the crypto qce (Qualcomm Crypto Engine) driver, specifically the devm_qce_register_algs function. The root cause is an error-path bug : when ops->register_algs() fails during algorithm registration, the error handler repeatedly invokes the same ops->u...
