CVE-2026-74571

CVE-2026-74571 affects the Linux kernel/btrfs. The issue occurs when mounting with rescue=ibadroots on a corrupted block group tree, leading to a NULL pointer dereference in btrfs_update_global_block_rsv. The root cause is that btrfs_read_roots() may leave a root pointer NULL while its on-disk fe...
