Linux Kernel Memory Leak Vulnerability in ms_block Component

A memory leak vulnerability has been identified in the Linux kernel's memstick/ms_block component. The issue arises because the 'erased_blocks_bitmap' is allocated simultaneously with the 'used_blocks_bitmap' but is never freed. This oversight creates a memory leak, as the allocated memory for 'erased_blocks_bitmap' is not released, potentially leading to increased memory usage over time.

Impact

Exploitation of this vulnerability leads to a memory leak, where allocated memory is not properly freed, potentially causing increased memory usage and degradation of system performance.
