CVE-2025-21943 – gpio: aggregator: protect driver attr handlers against module unload
https://notcve.org/view.php?id=CVE-2025-21943
01 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: gpio: aggregator: protect driver attr handlers against module unload Both new_device_store and delete_device_store touch module global resources (e.g. gpio_aggregator_lock). To prevent race conditions with module unload, a reference needs to be held. Add try_module_get() in these handlers. For new_device_store, this eliminates what appears to be the most dangerous scenario: if an id is allocated from gpio_aggregator_idr but platform_device_... • https://git.kernel.org/stable/c/828546e24280f721350a7a0dcc92416e917b4382 •

CVE-2025-21941 – drm/amd/display: Fix null check for pipe_ctx->plane_state in resource_build_scaling_params
https://notcve.org/view.php?id=CVE-2025-21941
01 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix null check for pipe_ctx->plane_state in resource_build_scaling_params Null pointer dereference issue could occur when pipe_ctx->plane_state is null. The fix adds a check to ensure 'pipe_ctx->plane_state' is not null before accessing. This prevents a null pointer dereference. Found by code review.
