Description
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: hci_cmd_sync_queue_once() return -EEXIST if exists
hci_cmd_sync_queue_once() needs to indicate whether a queue item was
added, so caller can know if callbacks are called, so it can avoid
leaking resources.
Change the function to return -EEXIST if queue item already exists.
Modify all callsites to handle that.
Affected configurations
• linux linux kernel (>= 6.9 < 6.19.12)
• linux linux kernel 6.1.120
• linux linux kernel 6.6.51
• linux linux kernel 6.8.9
• linux linux kernel 7.0
