CVE-2026-64144 Details
Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btmtk: fix urb->setup_packet leak in error paths The setup_packet of control urb is not freed if usb_submit_urb fails or the submitted urb is killed. Add free in these two paths.
A memory leak vulnerability has been identified in the Bluetooth driver for MediaTek MT7668U USB devices, specifically within the Linux kernel. The issue arises because the 'setup_packet' of control URBs (USB Request Blocks) is not properly freed when 'usb_submit_urb' fails or when the submitted URB is terminated. This oversight can lead to a resource leak, as the allocated memory for the 'setup_packet' remains unfreed under these error conditions.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is available in the Linux kernel stable tree.
