The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Validate CRIU-restored IDs before idr_alloc
The KFD CRIU restore flow restores previously saved object IDs from userspace.
For event restore:
kfd_criu_restore_event() -> create_signal_event() / create_other_event() -> allocate_event_notification_slot() -> idr_alloc(..., *restore_id, *restore_id + 1, ...)
For BO restore:
criu_restore_memory_of_gpu() -> idr_alloc(..., bo_priv->idr_handle, ...)
In both cases, the restored ID comes from userspace-provided CRIU data.
idr_alloc() expects the ID range values to fit within signed int limits. If a restored ID is larger than INT_MAX, it can trigger a WARN in the IDR layer.
A kernel WARN is undesirable because it prints a warning trace and may cause a panic or reboot on systems with panic_on_warn enabled.
Smatch reported these paths as allowing unchecked userspace values to reach idr_alloc().
Add INT_MAX validation before using restored IDs in:
If the restored ID is invalid, return -EINVAL.
This prevents invalid restore data from reaching the IDR layer and avoids WARN-triggering paths, while keeping valid restore behavior unchanged.
