Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_codec: Fix leaking content of local_codecs
The following memory leak can be observed when the controller supports
codecs which are stored in local_codecs list but the elements are never
freed:
unreferenced object 0xffff88800221d840 (size 32):
comm "kworker/u3:0", pid 36, jiffies 4294898739 (age 127.060s)
hex dump (first 32 bytes):
