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

Description The issue concerns the Linux kernel, specifically with loading 64-bit NOMMU kernels past the start of RAM. A commit added logic to allow using RAM below the kernel load address, but this does not work for NOMMU, where PAGE OFFSET is fixed to the kernel load address. As a result, mm initialization runs off the beginning of mem map and corrupts adjacent kernel memory. The fix involves restoring the previous behavior for NOMMU kernels.

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