CVE-2026-53251

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

Description An issue exists in the Bluetooth ISO component where the iso conn big sync function fails to release a reference to the hci dev pointer. This occurs because hci get route() returns a reference-counted pointer via hci dev hold(), but the function exits without releasing it, regardless of whether the execution is normal or results in an error.

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