Am really not sure if you are taking fixes late in this cycle. In case you are not could you please apply them for 6.2 Thanks, Srini Abel Vesa (2): misc: fastrpc: Fix use-after-free and race in fastrpc_map_find misc: fastrpc: Don't remove map on creater_process and device_release Ola Jeppsson (1): misc: fastrpc: Fix use-after-free race condition for maps drivers/misc/fastrpc.c | 67 ++++++++++++++++++++++-------------------- 1 file changed, 35 insertions(+), 32 deletions(-) -- 2.25.1
