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 not checking the block address of a non-inline pcluster, which could lead to a memory leak...

kernel: ext4: make sure the first directory block is not a hole

The syzbot constructs a directory that has no dirblock but is non-inline, i.e. the first directory block is a hole. And no errors are reported when creating files in this directory. Then, we get a directory block without '.' and '..' but with a valid dentry. This may cause some code that relies o...
