EUVD-2026-71627

A flaw was found in libtpms, a library that provides software TPM 2.0 emulation. When restoring TPM 2.0 state for example during a virtual machine's power-on or state/migration restore, a malformed state blob can supply an oversized skip-block length that is not validated against the remaining si...

sogen — Updated!

Sogen runs Windows and Linux programs without a real operating system, and lets you see and control everything they do. Instead of reimplementing thousands of OS APIs, Sogen emulates binaries at CPU and syscall level and runs the real system DLLs , so behavior closely matches the real OS. Every...

FreeRDP: FreeRDP: Denial of Service via crafted smartcard cache requests

A flaw was found in FreeRDP. When smartcard emulation is enabled, a remote attacker can send specially crafted smartcard cache requests to a FreeRDP client. This can lead to a null pointer dereference, causing the client process to terminate and disrupting active remote desktop sessions...
