virtio sound

The virtio sound tag covers discussions about the virtio-snd driver, which provides audio support in virtualized environments using the virtio paravirtualized device interface. A key topic is CVE-2025-37805, a security fix addressing uninitialized work_structs in the virtio_snd driver. This bug could trigger kernel workqueue warnings and disrupt system availability in virtualized setups like KVM/QEMU and cloud hypervisors. The fix ensures that cancel_work_sync() is not called on uninitialized objects, improving driver reliability. Content focuses on Linux kernel patches, virtualization stability, and security vulnerabilities related to virtio sound.
