CVE-2023-52451: powerpc/pseries/memhp: Fix access beyond end of drmem array

In the Linux kernel, the following vulnerability has been resolved:

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

dlparmemoryremovebyindex() 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 &drmeminfo->lmbs[drmeminfo->nlmbs], 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:

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

This was found by inspection and confirmed with KASAN:

Other sources

Linux Kernel is vulnerable to a denial of service, caused by an error related to access beyond end of drmem array. A local attacker could exploit this vulnerability to cause a denial of service.
