A use-after-free flaw was found in the Linux kernel’s SGI GRU driver in the
way the first gru_file_unlocked_ioctl function is called by the user, where
a fail pass occurs in the gru_check_chiplet_assignment function. This flaw
allows a local user to crash or potentially escalate their privileges on
the system.
