Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel where the early init dt scan memory function did not distinguish between successful and unsuccessful memory setup. This caused subsequent memory initialization mechanisms, such as those relying on the soc info.mem detect function pointer, to fail, leading to kernel panics during early bootup on certain boards. Specifically, systems dependent on soc info.mem detect for memory initialization would fail to allocate memory, resulting in an error message like "early init dt alloc memory arch: Failed to allocate 12416 bytes align=0x40".

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
