CVE-2023-52808
Hisi Sas Main Linux Kernel Debugfs Pointer Vulnerability
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: hisi_sas: Set debugfs_dir pointer to NULL after removing debugfs If init debugfs failed during device registration due to memory allocation failure, debugfs_remove_recursive() is called, after which debugfs_dir is not set to NULL. debugfs_remove_recursive() will be called again during device removal. As a result, illegal pointer is accessed. [ 1665.467244] hisi_sas_v3_hw 0000:b4:02.0: failed to init debugfs! ...
