In the Linux kernel, the following vulnerability has been resolved:
uio_hv_generic: Let userspace take care of interrupt mask
Remove the logic to set interrupt mask by default in uio_hv_generic
driver as the interrupt mask value is supposed to be controlled
completely by the user space. If the mask bit gets changed
by the driver, concurrently with user mode operating on the ring,
the mask bit may be set when it is supposed to be clear, and the
user-mode driver will miss an interrupt which will cause a hang.
For eg- when the driver sets inbound ring buffer interrupt mask to 1,
the host does not interrupt the guest on the UIO VMBus channel.
However, setting the mask does not prevent the host from putting a
message in the inbound ring buffer. So let’s assume that happens,
the host puts a message into the ring buffer but does not interrupt.
Subsequently, the user space code in the guest sets the inbound ring
buffer interrupt mask to 0, saying “Hey, I’m ready for interrupts”.
User space code then calls pread() to wait for an interrupt.
Then one of two things happens:
* The host never sends another message. So the pread() waits forever.
* The host does send another message. But because there’s already a
message in the ring buffer, it doesn’t generate an interrupt.
This is the correct behavior, because the host should only send an
interrupt when the inbound ring buffer transitions from empty to
not-empty. Adding an additional message to a ring buffer that is not
empty is not supposed to generate an interrupt on the guest.
Since the guest is waiting in pread() and not removing messages from
the ring buffer, the pread() waits forever.
This could be easily reproduced in hv_fcopy_uio_daemon if we delay
setting interrupt mask to 0.
Similarly if hv_uio_channel_cb() sets the interrupt_mask to 1,
there’s a race condition. Once user space empties the inbound ring
buffer, but before user space sets interrupt_mask to 0, the host could
put another message in the ring buffer but

uio_hv_generic: Let userspace take care of interrupt mask
Remove the logic to se
In the Linux kernel, the following vulnerability has been resolved:
uio_hv_generic: Let userspace take care of interrupt mask
Remove the logic to set interrupt mask by default in uio_hv_generic
driver as the interrupt mask value is supposed to be controlled
completely by the user space. If the mask bit gets changed
by the driver, concurrently with user mode operating on the ring,
the mask bit may be set when it is supposed to be clear, and the
user-mode driver will miss an interrupt which will cause a hang.
For eg- when the driver sets inbound ring buffer interrupt mask to 1,
the host does not interrupt the guest on the UIO VMBus channel.
However, setting the mask does not prevent the host from putting a
message in the inbound ring buffer. So let’s assume that happens,

kernel: uio_hv_generic: Let userspace take care of interrupt mask
vendor_redhat·2025-10-28·CVSS 6.2
CVE-2025-40048 [MEDIUM] CWE-362 kernel: uio_hv_generic: Let userspace take care of interrupt mask
kernel: uio_hv_generic: Let userspace take care of interrupt mask
In the Linux kernel, the following vulnerability has been resolved:
uio_hv_generic: Let userspace take care of interrupt mask
Remove the logic to set interrupt mask by default in uio_hv_generic
driver as the interrupt mask value is supposed to be controlled
completely by the user space. If the mask bit gets changed
by the driver, concurrently with user mode operating on the ring,
the mask bit may be set when it is supposed to be clear, and the
user-mode driver will miss an interrupt which will cause a hang.
For eg- when the driver sets inbound ring buffer interrupt mask to 1,
the host does not interrupt the guest on the UIO VMBus channel.
However, setting the mask does not prevent the host from putting a
message in the inbo

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.
