kernel: powerpc: Fix access beyond end of drmem array

A flaw was found in the Linux kernel, specifically affecting the PowerPC architecture's pseries memory hotplug functionality. The issue arises from the dlparmemoryremovebyindex function, which may access memory beyond the bounds of the drmem logical memory block LMB array when it fails to find a...

The vulnerability of the dlpar_memory_remove_by_index() function in the Linux operating system’s PowerPC PSeries kernel driver allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the dlparmemoryremovebyindex function in the Linux operating system’s PowerPC PSeries kernel memory driver relates to reading memory beyond the allocated buffer. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
