CVE-2024-50015

CVE-2024-50015 affects the Linux kernel ext4 dax path. In ext4/dax, the loop in dax_iomap_rw() can copy data after the process is signalled and then update the inode size, causing written extents to exceed the inode size (e.g., 2M vs 4M) and fsck to report inconsistencies. The referenced fixes tr...
