Subject: [PATCH] Fix potential abort in btu_av_act.cc
|
|
|
|
Partner analysis shows that bta_av_rc_msg does not respect handling
|
|
established for a null browse packet, instead dispatching the null
|
|
pointer to bta_av_rc_free_browse_msg. Strictly speaking this does
|
|
not cause a UAF, as osi_free_and_reset will find the null and abort,
|
|
but it will lead to improper program termination.
|
|
|
|
Handle the case instead.
