CLEANSTART-2026-UN38263 Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not

Security vulnerability affects the temporal-server package. Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not...

ALSA-2026:76918 Important: openssl security update

OpenSSL is a toolkit that implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols, as well as a full-strength general-purpose cryptography library. Security Fixes: openssl: compat-openssl: DTLS Retransmits Handshake Messages From a Stale Buffer Offset CVE-2026-84782 For...

Rustls: TLS 1.3 handshake messages incorrectly accepted across encryption level boundaries

Rustls accepted TLS 1.3 handshake messages sent at the wrong encryption level when they followed a key-changing message in the same record. The handshake transcript is still authenticated, so a network-position attacker cannot use this to alter or complete a handshake; the practical effect is tha...

netty-handler: Netty: Denial of Service due to eager buffer allocation in TLS handshake

A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a crafted TLS Transport Layer Security ClientHello message. This can lead to an eager allocation of a large memory buffer, causing a Denial of Service DoS due to excessive memor...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can result in the callback being fired later, thereby causing a use-after-free when using the channel. This vulnerability can be exploited by a malicious...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In the tcpdisconnect function, the tcpsksk-fastopenrsk field was not cleared. The syzbot reported that a socket had tcpsksk-fastopenrsk in the TCPESTABLISHED state. The syzbot reused the server-side TCP Fast Open socket as a new...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/ast: Fixed soft lockup issue There is a while-loop in astdpsetonoff, which could lead to an infinite loop. This is because the register, VGACRI-Dx, is checked in this API; it is actually a scratch register controlled by a MCU...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Mbed TLS 3.5.1. There is a persistent handshake denial if a client sends a TLS 1.3 ClientHello without extensions...

Astra Linux – Vulnerability in Golang-1.19

Large handshake records can cause panics in the crypto/TLS context. Both clients and servers may send large TLS handshake records, which can cause both servers and clients to panic when attempting to construct responses. This issue affects all TLS 1.3 clients, TLS 1.2 clients that explicitly enab...

Astra Linux – Vulnerability in gnutls28

A flaw in GnuTLS’ DTLS handshake parsing allows for malformed fragments with zero length and non-zero offsets. This leads to an integer underflow during reassembly, resulting in an out-of-bounds read. This issue is remotely exploitable and could cause information disclosure or denial of service...
