CVE-2026-66401

FreeRDP before 3.29.0 contains an out-of-bounds heap read vulnerability in the UVC H.264 extension-unit parser that fails to validate descriptor length before accessing the GUID field. A local attacker with a malicious USB video camera can trigger a heap read beyond allocated bounds during camera...

CVE-2026-66360 MZ Automation libiec61850 Out-of-bounds Read

The ISO Presentation layer contains a flaw in the handling of specific parameters during normal mode negotiation. A missing length check in the processing of the encoded presentation data allows an attacker controlled field with a zero length value to trigger a bounded heap over read. This...

CVE-2026-64552

Summary (CVE-2026-64552) In the Linux kernel virtio-net, receive_big() does a length check against (big_packets_num_skbfrags + 1) * PAGE_SIZE, but a gap remains due to add_recvbuf_big() placing sg[1] after the padded vnet header. A malicious virtio backend can announce a length in that gap, causi...
