Description
In the Linux kernel, the following vulnerability has been resolved:
EDAC/skx_common: Fix general protection fault
After loading i10nm_edac (which automatically loads skx_edac_common), if
unload only i10nm_edac, then reload it and perform error injection testing,
a general protection fault may occur:
mce: [Hardware Error]: Machine check events logged
Oops: general protection fault ...
...
Workqueue: events mce_gen_pool_process
RIP: 0010:string+0x53/0xe0
...
Call Trace:

skx_mce_check_error+0x17/0x20 [skx_edac_common]
...
The issue arose was because the variable 'adxl_component_count' (inside
skx_edac_common), which counts the ADXL components, was not reset. During
the reloading of i10nm_edac, the count was incremented by the actual number
of ADXL components again, resulting in a count that was double the real
number of ADXL components. This led to an out-of-bounds reference to the
ADXL component array, causing the general protection fault above.
Fix this issue by resetting the 'adxl_component_count' in adxl_put(),
which is called during the unloading of {skx,i10nm}_edac.
