Vulnerability from github
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: ? die_addr+0x37/0x90 ? exc_general_protection+0x1e7/0x3f0 ? asm_exc_general_protection+0x26/0x30 ? string+0x53/0xe0 vsnprintf+0x23e/0x4c0 snprintf+0x4d/0x70 skx_adxl_decode+0x16a/0x330 [skx_edac_common] skx_mce_check_error.part.0+0xf8/0x220 [skx_edac_common] 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.
