CVE-2023-54294 Details
Description
In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix memleak of md thread In raid10_run(), if setup_conf() succeed and raid10_run() failed before setting 'mddev->thread', then in the error path 'conf->thread' is not freed. Fix the problem by setting 'mddev->thread' right after setup_conf().
A memory leak vulnerability has been identified in the Linux kernel's RAID 10 implementation. The issue arises in the 'raid10_run()' function, where the 'mddev->thread' is not properly freed if the 'setup_conf()' function succeeds but 'raid10_run()' fails before assigning the thread. This vulnerability affects the Linux kernel RAID 10 module in several versions.
The vulnerability has been addressed by modifying the 'raid10_run()' function to set 'mddev->thread' immediately after the 'setup_conf()' call, ensuring that the thread is properly managed even if an error occurs later in the function.
