CVE-2026-68318

Service interruption via premature workqueue destruction

Published Aug 10, 2026 · Updated Aug 10, 2026

Use-after-free in the Linux pds_core driver allows local users to interrupt service during removal of a managed device. pdsc_remove() destroys its workqueue before pdsc_teardown(), while reset-timeout and NotifyQ interrupt paths can still queue health or admin work that touches teardown resources. Reachability requires local access and device teardown; the documented impact is limited to service availability.
