Ensure That Mounting for Unnecessary File System Is Removed

Linux supports multiple file systems through kernel objects loaded to the kernel. As a universal OS platform, openEuler provides various kernel object files in the /lib/modules/kernel version/kernel/fs/ directory to support different file systems. You can run the insmod or modprobe command to loa...

The vulnerability of the `ovl_dentry_update_reval()` function in the `fs/overlayfs/copy_up.c` file of the Linux kernel file system allows a attacker to cause a service failure.

The vulnerability of the ovldentryupdatereval function in the fs/overlayfs/copyup.c file of the Linux kernel file system is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to cause a service failure...

The vulnerability of the ovl_lookup() function in the fs/overlayfs/namei.c module of the Linux file system allows a hacker to gain access to protected information.

The vulnerability of the ovllookup function in the fs/overlayfs/namei.c module of the Linux file system supports the kernel’s file system support. This vulnerability is related to improper memory release before deleting the last reference memory leak. Exploiting this vulnerability can allow an...
