Hi Anant,
> When h5_close() gets called, the memory allocated for the hu gets > freed only if hu->serdev doesn't exist. This leads to a memory leak. > So when h5_close() is requested, close the serdev device instance and > free the memory allocated to the hu entirely instead. > > Fixes: https://syzkaller.appspot.com/bug?extid=6ce141c55b2f7aafd1c4 > Reported-by: syzbot+6ce141c55b2f7aafd1c4@syzkaller.appspotmail.com > Tested-by: syzbot+6ce141c55b2f7aafd1c4@syzkaller.appspotmail.com > Signed-off-by: Anant Thazhemadam <anant.thazhemadam@gmail.com> > --- > drivers/bluetooth/hci_h5.c | 8 ++++++-- > 1 file changed, 6 insertions(+), 2 deletions(-)
