In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Validate command header size against SVGACMDMAXDATASIZE This data originates from userspace and is used in buffer offset calculations; it may potentially overflow, leading to an out-of-bounds access...

Astra Linux – vulnerability in linux, linux-5.10, linux-5.15, linux-6.1

Requests transmitted via Xen’s virtual network protocol can consist of multiple parts. Although not really useful—except for the initial part—any of these parts may be of zero length, meaning they carry no data at all. Apart from a certain initial portion of the data to be transferred, these part...
