CVE-2026-43022

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the Bluetooth component where the hci cmd sync queue once() function fails to indicate whether a queue item was added. This prevents the caller from knowing if callbacks are executed, which can lead to resource leaks. The fix involves modifying the function to return -EEXIST when a queue item already exists and updating all callsites to handle this return value.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
