CVE-2026-33846

A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in mergehandshakepacket where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the messagelength field remains...

GnuTLS 安全漏洞

GnuTLS is an open-source, free security communication library developed by GnuTLS that enables the implementation of SSL, TLS, and DTLS protocols. GnuTLS has a security vulnerability, which stems from the mergehandshakepacket function in the DTLS handshake reassembly logic not verifying the...

CVE-2026-23307

A flaw was found in the Linux kernel's emsusb module. This vulnerability occurs because the system does not properly verify the length of messages it receives. An attacker could exploit this weakness by sending specially crafted messages, potentially causing the system to crash Denial of Service...

CVE-2026-23307

CVE-2026-23307 concerns the Linux kernel CAN/EMS USB code, where ems_usb_read_bulk_callback() failed to validate message lengths, reading beyond buffers because actual_length can exceed the expected transfer_buffer_length, risking overflow when parsing messages. The root cause is insufficient len...
