Astra Linux – Vulnerability in Qemu

A NULL pointer dereference flaw was discovered in the floppy disk emulator of QEMU. This issue occurs when processing read/write ioport commands, especially if the selected floppy drive is not initialized using a block device. This flaw allows a privileged guest user to crash the QEMU process on...

CVE-2023-53356

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: userial: Add null pointer check in gserialsuspend Consider a case where gserialdisconnect has already cleared gser-ioport. And if gserialsuspend gets called afterwards, it will lead to accessing of gser-ioport and th...

Privilege Escalation

xen is vulnerable to privilege escalation attacks. The vulnerability exists as the 1 ioportread and 2 ioportwrite functions in Xen, when qemu is used as a device model within Xen, might allow local x86 HVM guest OS administrators to gain qemu process privileges via vectors involving an out-of-ran...
