CVE-2026-44452

CVE-2026-44452 affects the h2o HTTP server (supports HTTP/1.x, 2, 3). Affected behavior occurs when a TLS/QUIC ClientHello contains a zero-length SNI extension; h2o can attempt to copy the hostname assuming NULL-termination, causing a heap/segmentation fault that may enable a denial-of-service. T...

CVE-2026-44436 Quicly is vulnerable to connection state corruption

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit 8b178e6, Quicly is vulnerable to a Denial of Service attack through connection state corruption. In QUIC Invariants, the maximum length of a Connection ID is 255 bytes, while QUIC...

EUVD-2026-44840

A flaw was found in QEMU. This vulnerability allows a local attacker within a guest virtual machine to write data beyond its allocated memory. This occurs when cpuphysicalmemorymap returns a shorter length than expected, leading to an out-of-bounds write. Successful exploitation could result in...
