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/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages
A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...

CVE-2026-93824
A flaw was found in the Linux kernel's Transport Layer Security TLS subsystem. A local user can trigger this vulnerability by configuring TLS keys on a network socket already attached to a Berkeley Packet Filter BPF socket map sockmap. This unsupported integration exposes latent flaws in the...
curl: curl: Insecure connection establishment due to TLS configuration mismatch
A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...
curl: libcurl: Improper certificate validation due to cached TLS settings reuse
A flaw was found in libcurl. When handling secure connections TLS and reusing connection settings, libcurl could incorrectly apply a cached security setting related to certificate chain validation. This could allow libcurl to accept a server's security certificate that it should have otherwise...
