CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's DRM subsystem, specifically in the `allocate_event_notification_slot` function, which fails to properly check the upper bounds of event IDs, potentially allowing for out-of-bounds access. This could lead to memory corruption or denial of service, impacting systems that utilize the kernel's graphics processing capabilities. Organizations using affected Linux distributions or F5 products should prioritize patching to mitigate potential exploitation risks.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check bounds in allocate_event_notification_slot The valid event ids go from 0 to KFD_SIGNAL_EVENT_LIMIT allocate_event_notification_slot has an option to specify an event id to allocate at, used by CRIU. We weren't checking the bounds on that value. Check them. v2: Lower bounds check is unecessary because of idr_alloc already rejecting negative numbers. Upper bounds check should be KFD_SIGNAL_EVENT_LIMIT since the signal mode mappings might not yet exist (cherry picked from commit 6853f1f6cbbeb3f53ebbbd7286536aeb2c5d5f50)
