panic: malloc: out of space in kmem_map
Status: fixed on 2019/05/21 04:34
Reported-by: syzbot+0b21fd31c3ee9d8363fa@syzkaller.appspotmail.com
Fix commit: During fuzzing, one or many fuzzing processes are often stuck waiting on memory from the subproc malloc subsystem which is exhausted. Attempt to circumvent such scenarios by allocation the kcov coverage buffer using km_alloc() instead.
First crash: 151d, last: 86d
