Kerentanan Incorrect Synchronization pada qemu, redhat enterprise linux. Skor CVSS 3.1 7.0 (High) menurut NVD.

Deskripsi (NVD)

A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
