Astra Linux - уязвимость в qemu

A flaw was discovered in the USB redirector device usb-redir of QEMU. Small USB packets are combined into a single, large transfer request, in order to reduce overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array VLA on th...

CVE-2026-24681

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, aAsynchronous bulk transfer completions can use a freed channel callback after URBDRC channel close, leading to a use after free in urbwritecompletion. This vulnerability is fixed in 3.22.0...
