About this tag
The work_struct tag on WindowsForum.com covers discussions about the Linux kernel workqueue mechanism, specifically focusing on the proper initialization and lifecycle management of work_struct objects. A key example is the CVE-2025-37805 vulnerability in the virtio sound driver, where uninitialized work_structs could trigger kernel workqueue warnings and disrupt system availability in virtualized environments. The fix ensures that cancel_work_sync() is never called on an uninitialized work_struct. This tag is relevant for developers and system administrators working with Linux kernel drivers, especially in virtualized or cloud settings using KVM/QEMU, where correct work_struct handling is critical for system stability.
