# The objcg is not cleared and put for kfence object when it is freed, # which could lead to memory leak for struct obj_cgroup and wrong # statistics of NR_SLAB_RECLAIMABLE_B or NR_SLAB_UNRECLAIMABLE_B. # # Since the last freed object's objcg is not cleared, # mem_cgroup_from_obj() could return the wrong memcg when this kfence # object, which is not charged to any objcgs, is reallocated to other # users. # # A real word issue [1] is caused by this bug. # # Link: https://lore.kernel.org/all/000000000000cabcb505dae9e577@google.com/ [1] # Reported-by: syzbot+f8c45ccc7d5d45fc5965@syzkaller.appspotmail.com #
