CVE-2026-90255

A flaw was found in the Linux kernel's Bluetooth subsystem. Specifically, a resource leak occurs in the handling of Synchronous Connection-Oriented (SCO) setup contexts. If a setup entry is cancelled, its associated context is not properly released, leading to a memory leak. This issue could also result in a use-after-free condition if a Bluetooth connection is freed while its pointer is still referenced in a queued work item, potentially leading to system instability or a denial of service.
