CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's Bluetooth implementation, specifically within the hci_le_big_terminate() function, which can lead to a memory leak due to improper handling of allocated resources when certain flags are not set. This could result in degraded system performance or potential denial of service over time. Organizations using Linux systems with Bluetooth capabilities should prioritize addressing this issue to maintain system stability and security.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_conn: Fix memory leak in hci_le_big_terminate() hci_le_big_terminate() allocates iso_list_data via kzalloc_obj but returns 0 without freeing it when neither pa_sync_term nor big_sync_term flags are set after evaluating the PA and BIG sync connection state. This early-return path was introduced when hci_le_big_terminate() was refactored to take struct hci_conn instead of raw u8 parameters, adding PA/BIG flag evaluation logic. The existing kfree() on hci_cmd_sync_queue failure does not cover this path.
