CVE-2022-50435

A flaw was found in the ext4 filesystem implementation in the Linux kernel. When a file is created and written via direct I/O (DIO), the flag EXT4_STATE_MAY_INLINE_DATA is not cleared. Subsequently, if the inode is truncated and then written using buffered I/O, the filesystem may attempt to store inline data and normal blocks for the same inode. This inconsistent state may lead to a kernel crash (BUG) or panic.
