 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:powerpc/pseries/memhp: Fix access beyond end of drmem arraydlpar_memory_remove_by_index() may access beyond the bounds of thedrmem lmb array when the LMB lookup fails to match an entry with thegiven DRC index. When the search fails, the cursor is left pointing to&drmem_info->lmbs[drmem_info->n_lmbs], which is one element past thelast valid entry in the array. The debug message at the end of thefunction then dereferences this pointer:        pr_debug( Failed to hot-remove memory at %llx n ,                 lmb->base_addr);This was found by inspection and confirmed with KASAN:  pseries-hotplug-mem: Attempting to hot-remove LMB, drc index 1234  ==================================================================  BUG: KASAN: slab-out-of-bounds in dlpar_memory+0x298/0x1658  Read of size 8 at addr c000000364e97fd0 by task bash/949  dump_stack_lvl+0xa4/0xfc (unreliable)  print_report+0x214/0x63c  kasan_report+0x140/0x2e0  __asan_load8+0xa8/0xe0  dlpar_memory+0x298/0x1658  handle_dlpar_errorlog+0x130/0x1d0  dlpar_store+0x18c/0x3e0  kobj_attr_store+0x68/0xa0  sysfs_kf_write+0xc4/0x110  kernfs_fop_write_iter+0x26c/0x390  vfs_write+0x2d4/0x4e0  ksys_write+0xac/0x1a0  system_call_exception+0x268/0x530  system_call_vectored_common+0x15c/0x2ec  Allocated by task 1:   kasan_save_stack+0x48/0x80   kasan_set_track+0x34/0x50   kasan_save_alloc_info+0x34/0x50   __kasan_kmalloc+0xd0/0x120   __kmalloc+0x8c/0x320   kmalloc_array.constprop.0+0x48/0x5c   drmem_init+0x2a0/0x41c   do_one_initcall+0xe0/0x5c0   kernel_init_freeable+0x4ec/0x5a0   kernel_init+0x30/0x1e0   ret_from_kernel_user_thread+0x14/0x1c  The buggy address belongs to the object at c000000364e80000   which belongs to the cache kmalloc-128k of size 131072  The buggy address is located 0 bytes to the right of   allocated 98256-byte region [c000000364e80000, c000000364e97fd0)  ==================================================================  pseries-hotplug-mem: Failed to hot-remove memory at 0Log failed lookups with a separate message and dereference thecursor only when it points to a valid entry.

CVE-2023-52451

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

powerpc/pseries/memhp: Fix access beyond end of drmem array

dlpar_memory_remove_by_index() may access beyond the bounds of the
drmem lmb array when the LMB lookup fails to match an entry with the
given DRC index. When the search fails, the cursor is left pointing to
&drmem_info->lmbs[drmem_info->n_lmbs], which is one element past the
last valid entry in the array. The debug message at the end of the
function then dereferences this pointer:

pr_debug("Failed to hot-remove memory at %llx\n",
                 lmb->base_addr);

This was found by inspection and confirmed with KASAN:
