CVE-2022-49469

CVE-2022-49469 is a Linux kernel issue affecting the btrfs subsystem. The vulnerability arises in create_subvol() where, on failures of btrfs_qgroup_inherit(), btrfs_alloc_tree_block, or btrfs_insert_root(), anon_dev could leak because error handling did not free it. The fix reorganizes the error...
