Description Pedro Sampaio 2018-09-19 19:32:10 UTC 
A flaw was found in the Linux kernel in the hid_debug_events_read() function in the drivers/hid/hid-debug.c file. A lack of the certain checks may allow a privileged user ("root") to achieve an out-of-bounds write and thus receiving userspace buffer corruption.

Note: this fix introduces another vulnerability CVE-2019-3819/bz1669187 and these both should be fixed.
