EDAC/i10nm: Skip DIMM enumeration on a disabled memory controller
In the Linux kernel, the following vulnerability has been resolved:
EDAC/i10nm: Skip DIMM enumeration on a disabled memory controller
When loading the i10nm_edac driver on some Intel Granite Rapids servers,
a call trace may appear as follows:
UBSAN: shift-out-of-bounds in drivers/edac/skx_common.c:453:16
shift exponent -66 is negative
...
__ubsan_handle_shift_out_of_bounds+0x1e3/0x390
skx_get_dimm_info.cold+0x47/0xd40 [skx_edac_common]
i10nm_get_dimm_config+0x23e/0x390 [i10nm_edac]
skx_register_mci+0x159/0x220 [skx_edac_common]
i10nm_init+0xcb0/0x1ff0 [i10nm_edac]
...
This occurs because some BIOS may disable a memory controller if there
aren't any memory DIMMs populated on this memory controller. The DIMMMTR
register of this disabled memory controller contains the invalid value
~0, resulting in the call trace above.
Fix this call trace by skipping DIMM enumeration on a disabled memory
controller.
