Astra Linux – Vulnerability in Qemu

A flaw was discovered in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. This flaw occurs when dropping packets during a bulk transfer from a SPICE client, due to the packet queue being full. A malicious SPICE client could exploit this flaw to call the free function in...
