  Bluetooth: hci_core: Fix use-after-free in vhci_flush() (2025-06-23 10:59:29 -0400)

----------------------------------------------------------------
bluetooth pull request for net:

 - L2CAP: Fix L2CAP MTU negotiation
 - hci_core: Fix use-after-free in vhci_flush()

I think this could use a net-next follow-up adding sparse annotation for
the newly introduced helpers:

./net/bluetooth/hci_core.c:85:9: warning: context imbalance in
'__hci_dev_get' - different lock contexts for basic block
../net/bluetooth/hci_core.c: note: in included file (through
../include/linux/notifier.h, ../arch/x86/include/asm/uprobes.h,
../include/linux/uprobes.h, ../include/linux/mm_types.h,
../include/linux/mmzone.h, ../include/linux/gfp.h, ...):
../include/linux/srcu.h:400:9: warning: context imbalance in
'hci_dev_put_srcu' - unexpected unlock

(not intended to block this PR!)

Can you address the above comments?

For sure, will send a followup.
