- Summary
- scsi: hisi_sas: Set debugfs_dir pointer to NULL after removing debugfs
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
scsi: hisisas: Set debugfsdir pointer to NULL after removing debugfs
If init debugfs failed during device registration due to memory allocation failure, debugfsremoverecursive() is called, after which debugfsdir is not set to NULL. debugfsremove_recursive() will be called again during device removal. As a result, illegal pointer is accessed.
