Under unsupported use of the interface, a use-after-free condition may occur that can lead to kernel memory corruption, platform instability, or system reboot.\n\n\n\nThe weakness occurs when software references memory after it has been released. Accessing memory after free may result in corruption of valid data structures, unexpected program behaviour, process crashes, or execution of unintended operations.\n\n## Affected\n\n- `graphics_ddk 1.18 RTM2`\n- `graphics_ddk 23.2 RTM2`\n- `graphics_ddk 24.2 RTM2`\n- `graphics_ddk 25.1 RTM2`\n- `graphics_ddk 25.3 RTM`\n- `graphics_ddk 26.1 RTM2`\n- `graphics_ddk 26.2 RTM`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
