UBUNTU-CVE-2024-57946: Medium severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: virtio-blk: don't keep queue frozen during system suspend Commit 4ce6e2db00de ("virtio-blk: Ensure no requests in virtqueues before deleting vqs.") replaces queue quiesce with queue freeze in virtio-blk's PM callbacks. And the motivation is to drain inflight IOs before suspending. block layer's queue freeze looks very handy, but it is also easy to cause deadlock, such as, any attempt to call into bioqueueenter() may run into deadlock if the queue is frozen in current context. There are all kinds of ->suspend() called in suspend context, so keeping queue frozen in the whole suspend context isn't one good idea. And Marek reported lockdep warning[1] caused by virtio-blk's freeze queue in virtblkfreeze(). [1] https://lore.kernel.org/linux-block/ca16370e-d646-4eee-b9cc-87277c89c43c@samsung.com/ Given the motivation is to drain in-flight IOs, it can be done by calling freeze & unfreeze, meantime restore to previous behavior by keeping queue quiesced during suspend.

For virtio-blk system suspend, drain in-flight I/O by calling queue freeze and unfreeze, then keep the queue quiesced during the suspend context rather than frozen for the entire suspend operation.
Event History
Frequently Asked Questions
Which Ubuntu kernel packages are listed as affected?
The listed Ubuntu kernel packages are linux, linux-aws, linux-azure, linux-gcp, linux-ibm, linux-oracle, linux-raspi, and linux-realtime.
When can this issue be triggered?
It is associated with virtio-blk power-management suspend handling. The problematic condition arises when the block queue remains frozen throughout system suspend and code in the suspend context attempts to enter the queue through bio_queue_enter().
What is the availability impact?
The issue can cause a deadlock during system suspend, resulting in an availability impact. The provided vector rates availability as high while confidentiality and integrity are unaffected.
What behavior does the fix restore?
The fix freezes and unfreezes the queue only to drain in-flight I/O, then keeps the queue quiesced during suspend rather than frozen for the full suspend context.
