CVE-2022-2308
CVE-2022-2308 describes a vulnerability in the Linux kernel’s vDPA with the VDUSE backend. The VDUSE kernel driver does not validate that the device config space size matches the features advertised by the VDUSE userspace app, causing Virtio config read helpers to pass uninitialized memory to vdu...
CVE-2022-2308: Use of Uninitialized Variable
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 t...
