CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel on DSI 6G platforms, where improper handling of the IO address space during memory dumping can lead to unauthorized access to unmapped memory regions. This flaw could potentially allow attackers to read sensitive data or cause system instability. Organizations using affected Linux kernel versions, particularly those leveraging DSI 6G hardware, should prioritize applying the patch to mitigate risks associated with this vulnerability.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/dsi: don't dump registers past the mapped region On DSI 6G platforms the IO address space is internally adjusted by io_offset. Later this adjusted address might be used for memory dumping. However the size that is used for memory dumping isn't adjusted to account for the io_offset, leading to the potential access to the unmapped region. Lower ctrl_size by the io_offset value to prevent access past the mapped area. msm_disp_snapshot_add_block+0x1d4/0x3c8 [msm] (P) msm_dsi_host_snapshot+0x4c/0x78 [msm] msm_dsi_snapshot+0x28/0x50 [msm] msm_disp_snapshot_capture_state+0x74/0x140 [msm] msm_disp_snapshot_state_sync+0x60/0x90 [msm] _msm_disp_snapshot_work+0x30/0x90 [msm] kthread_worker_fn+0xdc/0x460 kthread+0x120/0x140 Patchwork: https://patchwork.freedesktop.org/patch/721747/
