NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-modules-usb package and not the kernel-uek-modules-usb package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

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

tracing: Take the reference before publishing the named histogram trigger

event_hist_trigger_named_init() puts the trigger on the global named_triggers list and only then takes the reference on the trigger it shares its histogram with:

data-&gt;ref++;

save_named_trigger(data-&gt;named_data-&gt;name, data);

ret = event_hist_trigger_init(data-&gt;named_data); if (ret &lt; 0) { kfree(data-&gt;cmd_ops); data-&gt;cmd_ops = &amp;trigger_hist_cmd; }

return ret;

event_hist_trigger_init() fails when alloc_hist_pad() cannot allocate, and nothing takes the trigger back off the list on the way out. event_hist_trigger_parse() frees it, and the next lookup by name reads the freed object:

BUG: KASAN: slab-use-after-free in find_named_trigger+0xac/0xc0 Read of size 8 at addr ffff888009346860 by task init/1 find_named_trigger+0xac/0xc0 hist_register_trigger+0xc1/0xa00 event_hist_trigger_parse+0x3146/0x6af0 event_trigger_write+0xce/0x160 Freed by task 67: kfree+0x154/0x420 trigger_kthread_fn+0xfd/0x160

Do the reference first and publish once it has succeeded, so that nothing which can fail runs after the trigger becomes findable.
