CVE-2026-31666
CVE-2026-31666 affects the Linux kernel’s btrfs filesystem. A defect in lookup_extent_data_ref() caused an incorrect return value when transitioning between leaves, due to merged err/ret handling: if btrfs_next_leaf() returns 0, ret could be overwritten from -ENOENT to 0, making a non-matching ke...
