CVE-2026-45934

CVE-2026-45934 covers a Linux kernel btrfs issue where non-consecutive gaps in chunk allocation can create overlapping chunk maps, leading to aborts of filesystem operations (e.g., insert_dev_extents in btrfs_create_pending_block_groups) and a DoS-like effect. Public records describe the root cau...
