NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-qemu-6.18 package and not the linux-qemu-6.18 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

A flaw was found in vDPA with VDUSE backend. There are currently no checks in VDUSE kernel driver to ensure the size of the device config space is in line with the features advertised by the VDUSE userspace application. In case of a mismatch, Virtio drivers config read helpers do not initialize the memory indirectly passed to vduse_vdpa_get_config() returning uninitialized memory from the stack. This could cause undefined behavior or data leaks in Virtio drivers.
