| Doc Text: |
A flaw was found in the MD driver, where the io_acct_set bioset was being allocated and freed within the personality module. However, additional free operations were incorrectly implemented in the md_free and md_stop functions. This redundancy led to a double-free condition, potentially causing memory corruption or system instability.
