A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

eventfs: Use list_del_rcu() for SRCU protected list variable

Chi Zhiling reported:

We found a null pointer accessing in tracefs[1], the reason is that the variable 'ei_child' is set to LIST_POISON1, that means the list was removed in eventfs_remove_rec. so when access the ei_child->is_freed, the panic triggered.

by the way, the following script can reproduce this panic

loop1 (){ while true do echo "p:kp submit_bio" > /sys/kernel/debug/tracing/kprobe_events echo "" > /sys/kernel/debug/tracing/kprobe_events done } loop2 (){ while true do tree /sys/kernel/debug/tracing/events/kprobes/ done } loop1 & loop2
