In the Linux kernel, the following vulnerability has been resolved:
vhost_task: Handle SIGKILL by flushing work and exiting
Instead of lingering until the device is closed, this has us handle
SIGKILL by:
1. marking the worker as killed so we no longer try to use it with
new virtqueues and new flush operations.
2. setting the virtqueue to worker mapping so no new works are queued.
3. running all the exiting works.

CVE-2024-42135 [MEDIUM] CWE-833 kernel: vhost_task: Handle SIGKILL by flushing work and exiting
kernel: vhost_task: Handle SIGKILL by flushing work and exiting
In the Linux kernel, the following vulnerability has been resolved:
vhost_task: Handle SIGKILL by flushing work and exiting
Instead of lingering until the device is closed, this has us handle
SIGKILL by:
1. marking the worker as killed so we no longer try to use it with
new virtqueues and new flush operations.
2. setting the virtqueue to worker mapping so no new works are queued.
3. running all the exiting works.
A vulnerability was discovered in the Linux kernel's vhost driver where the improper handling of SIGKILL signals can leave vhost workers lingering or performing unintended operations even after receiving the kill signal. This can lead to system instability or crashes.

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.
