CVE-2025-40051 [MEDIUM] CWE-703 kernel: vhost: vringh: Modify the return value check
kernel: vhost: vringh: Modify the return value check
In the Linux kernel, the following vulnerability has been resolved:
vhost: vringh: Modify the return value check
The return value of copy_from_iter and copy_to_iter can't be negative,
check whether the copied lengths are equal.
Statement: vringh incorrectly treated copy_from_iter() as potentially negative and only checked ret < 0. Since copy_from_iter() returns the number of bytes copied (non-negative), short/partial copies were falsely accepted, risking use of incomplete data and subsequent corruption/instability. The fix checks size != translated and returns -EFAULT on mismatch, properly handling faults/short copies in the vhost IOTLB translation path.
Exploitation requires local access to the vhost/virtio datapath — i.e. a process t

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
