CVE-2022-3424

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.

Mitigation

To mitigate this issue, prevent the module gru from being loaded. Please see <https://access.redhat.com/solutions/41278&gt; for information on how to blacklist a kernel module to prevent it from loading automatically.
