Subject: [PATCH] core: fix invalid free() in killall()
|
||
|
|
|
||
|
|
static int killall(....) in ./src/core/killall.c tries to get "s"
|
||
|
|
initialized by calling get_process_comm(...) which calls
|
||
|
|
read_one_line_file(...) which if it fails will mean it is left
|
||
|
|
uninitialized.
|
||
|
|
It is then used in argument to strna(s) call where it is
|
||
|
|
dereferenced(!), in addition to nothing else initializing it before
|
||
|
|
the scope it is in finishes.
