https://notcve.org/view.php?id=CVE-2024-49912
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Handle null 'stream_status' in 'planes_changed_for_existing_stream' This commit adds a null check for 'stream_status' in the function 'planes_changed_for_existing_stream'. Previously, the code assumed 'stream_status' could be null, but did not handle the case where it was actually null. This could lead to a null pointer dereference. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:3784 planes_changed_for_existing_stream() error: we previously assumed 'stream_status' could be null (see line 3774) • https://git.kernel.org/stable/c/c4b699b93496c423b0e5b584d4eb4ab849313bcf https://git.kernel.org/stable/c/4778982c73d6c9f3fdbdbc6b6c8aa18df98251af https://git.kernel.org/stable/c/ec6c32b58e6c4e87760e797c525e99a460c82bcb https://git.kernel.org/stable/c/0ffd9fb03bbc99ed1eb5dc989d5c7da2faac0659 https://git.kernel.org/stable/c/8141f21b941710ecebe49220b69822cab3abd23d •

https://notcve.org/view.php?id=CVE-2024-49911
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func This commit adds a null check for the set_output_gamma function pointer in the dcn20_set_output_transfer_func function. Previously, set_output_gamma was being checked for null at line 1030, but then it was being dereferenced without any null check at line 1048. This could potentially lead to a null pointer dereference error if set_output_gamma is null. To fix this, we now ensure that set_output_gamma is not null before dereferencing it. We do this by adding a null check for set_output_gamma before the call to set_output_gamma at line 1048. • https://git.kernel.org/stable/c/02411e9359297512946705b1cd8cf5e6b0806fa0 https://git.kernel.org/stable/c/827380b114f83c30b3e56d1a675980b6d65f7c88 https://git.kernel.org/stable/c/62ed6f0f198da04e884062264df308277628004f •

https://notcve.org/view.php?id=CVE-2024-49908
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2) This commit adds a null check for the 'afb' variable in the amdgpu_dm_update_cursor function. Previously, 'afb' was assumed to be null at line 8388, but was used later in the code without a null check. This could potentially lead to a null pointer dereference. Changes since v1: - Moved the null check for 'afb' to the line where 'afb' is used.
