From a9cdc85839e4fe2c760aa4ca6cc341c31ad1918a Mon Sep 17 00:00:00 2001 From: David Francis Date: Tue, 21 Jul 2026 09:30:07 -0400 Subject: [PATCH] drm/amdkfd: Handle invalid event type in CRIU event restore In kfd_criu_restore_event, there was no handling for the event priv data having an invalid event type. The priv data here is untrusted and can be invalid. In that case, fail with EINVAL.
