Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.19.0-rc8-00001-g31ba1e3b8305

Description The Linux kernel contained a flaw within the ext4 filesystem implementation. Specifically, a crash could occur when attempting to create inline data following a direct I/O (DIO) write operation. This happens because the EXT4 STATE MAY INLINE DATA flag was not being cleared after a DIO write, leading to confusion when the inode was truncated and a normal write was attempted. This confusion manifested as a kernel bug during writepage operations.

Recommendations Update to Linux kernel version 5.19.0-rc8-00001-g31ba1e3b8305 or a later version that includes the fix.
