Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from a failure to check the debugfsdir pointer before using it, resulting in a null pointer dereference when...

CVE-2023-52808

Summary: CVE-2023-52808 affects the Linux kernel driver path for the Hisilicon SAS host bus adapter (hisi_sas). The root cause is that after a failed init path, debugfs_remove_recursive() is called but debugfs_dir is not set to NULL, causing a NULL pointer dereference during device removal. Impac...
