Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: sound/virtio: Fix cancel_sync warnings
 on uninitialized work_structs Betty reported hitting the following warning: [ 8.709131][ T221] WARNING:
 CPU: 2 PID: 221 at kernel/workqueue.c:4182 ... [ 8.713282][ T221] Call trace: [ 8.713365][ T221]

 ab15f34d0dd772f6d11327e08a81d46dc9c36276] [ 8.714035][ T221] virtio_dev_probe+0x28c/0x390 [ 8.714139][
 T221] really_probe+0x1bc/0x4c8 ... It seems we're hitting the error path in virtsnd_probe(), which
 triggers a virtsnd_remove() which iterates over the substreams calling cancel_work_sync() on the
 elapsed_period work_struct. Looking at the code, from earlier in:
 virtsnd_probe()->virtsnd_build_devs()->virtsnd_pcm_parse_cfg() We set snd->nsubstreams, allocate the
 snd->substreams, and if we then hit an error on the info allocation or something in
 virtsnd_ctl_query_info() fails, we will exit without having initialized the elapsed_period work_struct.
 When that error path unwinds we then call virtsnd_remove() which as long as the substreams array is
 allocated, will iterate through calling cancel_work_sync() on the uninitialized work struct hitting this
 warning. Takashi Iwai suggested this fix, which initializes the substreams structure right after
 allocation, so that if we hit the error paths we avoid trying to cleanup uninitialized data. Note: I have
 not yet managed to reproduce the issue myself, so this patch has had limited testing. Feedback or thoughts
 would be appreciated! (CVE-2025-37805)
