[SRU K,HWE-5.17,J,OEM-5.14,F,B 0/1] CVE-2022-3564

[Thadeu Lima de Souza Cascardo]

[Impact]
A race condition on Bluetooth L2CAP can lead to a use-after-free.

[Backport]
The fix is in linux-next. It could be cherry-picked cleanly on all kernels,
though git-am would not apply to focal and bionic, which required their own
cherry-pick.

[Potential regression]
Bluetooth devices might fail to connect.
