CVE-2025-40190

CVE-2025-40190 affects the Linux kernel ext4: EA inode refcount underflow during xattr updates. The root cause is in ext4_xattr_inode_update_ref(), where a non-positive refcount could be decremented (ref_change -1), leading to underflow and errors. The fix enforces that if the current refcount is...
