CVE-2025-40167

An issued CVE (CVE-2025-40167) affects the Linux kernel ext4 implementation where an inode incorrectly has both INLINE_DATA and EXTENTS flags set. Connected sources describe the root cause: the combination causes ext4_has_inline_data() to return true, causing the extent-tree validation to be skip...
